Hashimoto's encephalopathy presenting as pseudobulbar palsy.

INTRODUCTION: Hashimoto's encephalopathy (HE) is an autoimmune condition with varied neurological and psychiatric features. HE is very unusual as a cause of pseudobulbar palsy (PSP). CASE PRESENTATION: A 14-year-old male was admitted with right-sided weakness, dysphagia, speech disorder, and aggressiveness. Brain magnetic resonance imaging showed increased intensity in bilateral temporal, insular cortex, amygdala, and parahippocampal area on T2-weighted and fluid-attenuated inversion recovery images. Autoimmune encephalitis was considered as the patient had subacute onset of psychiatric and motor disturbances with normal findings for cerebrospinal fluid. N-methyl-D-aspartate receptor, anti-glutamate-type α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid 1 and 2, anti-contactin-associated protein-like 2, anti-gamma-aminobutyric acid receptor, anti-Leucine-rich, and glioma-inactivated 1 antibodies were negative but the anti-thyroperoxidase (antiTPO) level was greater than 998 IU/ML (n:0-9). Steroid therapy was initiated as pulse therapy and maintained with 2-mg/kg/day dose with the diagnosis of HE. He was symptom free for 6 months. In the follow-up period, he had two recurrences which responded to steroid therapy. CONCLUSION: The common causes of PSP are demyelinating, vascular, and motor neuron diseases and congenital malformations of the opercular or insular cortex. However, there are no cases of PSP developing after any autoimmune encephalitis. This case highlights the importance of early detection of antiTPO antibodies with the findings of PSP due to autoimmune encephalitis.

Identification of pseudobulbar affect symptoms in the nursing home setting: Development and assessment of a screening tool.

Pseudobulbar Affect (PBA) is a neurologic condition characterized by involuntary outbursts of crying and/or laughing disproportionate to patient mood or social context. Although an estimated 9% of nursing home residents have symptoms suggestive of PBA, they are not routinely screened. Our goal was to develop an electronic screening tool based upon characteristics common to nursing home residents with PBA identified through medical record data. Nursing home residents with PBA treated with dextromethorphan hydrobromide/quinidine sulfate (n = 140) were compared to age-, gender-, and dementia-diagnosis-matched controls without PBA or treatment (n = 140). Comparative categories included diagnoses, medication use and symptom documentation. Using a multivariable regression and best decision rule analysis, we found PBA in nursing home residents was associated with chart documentation of uncontrollable crying, presence of a neurologic disorder (e.g., Parkinson's disease), or by the documented presence of at least 2 of the following: stroke, severe cognitive impairment, and schizophrenia. Based on these risk factors, an electronic screening tool was created.

Laughter, crying and sadness in ALS.

BACKGROUND: Pseudobulbar affect (PBA) is prevalent in amyotrophic lateral sclerosis (ALS), but there is limited information on its associations and course. OBJECTIVES: Explore prevalence, associations, course and manifestations of PBA in outpatient cohort of patients with ALS and examine its relationship to depression. METHODS: Self-reported measures of PBA and depression (Center for Neurologic Study-Lability Scale (CNS-LS) and Patient Health Questionnaire (PHQ-9), respectively) were obtained from consecutive patients with ALS using tablet devices in waiting rooms (Knowledge Program). RESULTS: PBA (CNS-LS ≥13) was seen in 209/735 patients (28.4%). PBA was associated with bulbar onset and dysfunction, upper motor neuron dysfunction, cognitive impairment, depression and lower quality of life. A multivariable model that included lower bulbar and gross motor subscores, female gender, younger age and shorter duration of disease predicted PBA with 74% accuracy. CNS-LS scores increased only slowly with time. Women with PBA reported more crying than men. Crying (but not laughter) correlated with depression, and crying was associated with poorer quality of life. Exploratory factor analysis of pooled questions of CNS-LS and PHQ-9 identified three underlying factors (laughter, crying and depression) loaded on appropriate questions of the respective instruments. CONCLUSION: This study identifies associations of PBA and additionally finds PBA (especially crying-predominant PBA) more prevalent in women with ALS. Although the two self-report instruments (CNS-LS and PHQ-9) discriminate well between PBA and depression, there is significant overlap between depression and crying in PBA. Studies of PBA should stratify for gender, examine crying and laughter as separate outcomes and adjust for depression.

PRISM II: an open-label study to assess effectiveness of dextromethorphan/quinidine for pseudobulbar affect in patients with dementia, stroke or traumatic brain injury.

BACKGROUND: Phase 3 trials supporting dextromethorphan/quinidine (DM/Q) use as a treatment for pseudobulbar affect (PBA) were conducted in patients with amyotrophic lateral sclerosis (ALS) or multiple sclerosis (MS). The PRISM II study provides additional DM/Q experience with PBA secondary to dementia, stroke, or traumatic brain injury (TBI). METHODS: Participants in this open-label, multicenter, 90-day trial received DM/Q 20/10 mg twice daily. The primary outcome was the Center for Neurologic Study-Lability Scale (CNS-LS), assessing change in PBA episode frequency and severity. The CNS-LS final visit score was compared to baseline (primary analysis) and to the response in a previously conducted placebo-controlled trial with DM/Q in patients with ALS or MS. Secondary outcomes included change in PBA episode count and Clinical Global Impression of Change with respect to PBA as rated by a clinician (CGI-C) and by the patient or caregiver (PGI-C). RESULTS: The study enrolled 367 participants with PBA secondary to dementia, stroke, or TBI. Mean (standard deviation [SD]) CNS-LS score improved significantly from 20.4 (4.4) at baseline to 12.8 (5.0) at Day 90/Final Visit (change, -7.7 [6.1]; P < .001, 95 % CI: -8.4, -7.0). This magnitude of improvement was consistent with DM/Q improvement in the earlier phase-3, placebo-controlled trial (mean [95 % CI] change from baseline, -8.2 [-9.4, -7.0]) and numerically exceeds the improvement seen with placebo in that study (-5.7 [-6.8, -4.7]). Reduction in PBA episode count was 72.3 % at Day 90/Final Visit compared with baseline (P < .001). Scores on CGI-C and PGI-C showed that 76.6 and 72.4 % of participants, respectively, were "much" or "very much" improved with respect to PBA. The most frequently occurring adverse events (AEs) were diarrhea (5.4 %), headache (4.1 %), urinary tract infection (2.7 %), and dizziness (2.5 %); 9.8 % had AEs that led to discontinuation. Serious AEs were reported in 6.3 %; however, none were considered treatment related. CONCLUSIONS: DM/Q was shown to be an effective and well-tolerated treatment for PBA secondary to dementia, stroke, or TBI. The magnitude of PBA improvement was similar to that reported in patients with PBA secondary to ALS or MS, and the adverse event profile was consistent with the known safety profile of DM/Q. TRIAL REGISTRATION: Clinicaltrials.gov, NCT01799941, registered on 25 February 2013.

Recognizing and treating pseudobulbar affect.

Pseudobulbar affect, thought by many to be a relatively newly described condition, is in fact a very old one, described as early as the 19th century. It refers to those who experience inappropriate affect, disconnected from internal state, or mood, generally thought to be the result of an upper motor neuron injury or illness. One possible explanation for this condition's relative obscurity is the dearth of treatment options; clinical medicine is not typically in the habit of identifying conditions that cannot be modified. Now, however, there is good evidence for the treatment of pseudobulbar affect, and even a therapy approved for use by the U.S. Food and Drug Administration (FDA). As a result, appropriate identification and subsequent management of pseudobulbar affect is more important than ever. This article purports to summarize the origins of pseudobulbar affect, most current hypotheses as to its physiopathology, clinical identification, and evidence for management.

Dextromethorphan-quinidine-responsive pseudobulbar affect (PBA): psychopharmacological model for wide-ranging disorders of emotional expression?

The symptoms of emotional dysregulation associated with the syndrome known as pseudobulbar affect (PBA) can be effectively treated by the sigma, glutamate, and serotonergic agent dextromethorphan combined with quinidine. If the same brain circuits affected in PBA are also compromised in related disorders of emotional expression, dextromethorphan-quinidine and other novel sigma-glutamate-serotonin agents could prove to be novel psychopharmacologic treatments for these conditions as well.

An open-label study to assess safety, tolerability, and effectiveness of dextromethorphan/quinidine for pseudobulbar affect in dementia: PRISM II results.

BACKGROUND: Dextromethorphan (DM)/quinidine (Q) is an approved treatment for pseudobulbar affect (PBA) based on trials in amyotrophic lateral sclerosis or multiple sclerosis. PRISM II evaluated DM/Q effectiveness and tolerability for PBA secondary to dementia, stroke, or traumatic brain injury; dementia cohort results are reported. METHODS: This was an open-label, multicenter, 90 day trial; patients received DM/Q 20/10 mg twice daily. Primary outcome was change in Center for Neurologic Study-Lability Scale (CNS-LS) score. Secondary outcomes included PBA episode count and Clinical and Patient/Caregiver Global Impression of Change scores with respect to PBA (CGI-C/PGI-C). RESULTS: 134 patients were treated. CNS-LS improved by a mean (SD) of 7.2 (6.0) points at Day 90/Endpoint (P<.001) vs. baseline. PBA episodes were reduced 67.7% (P<.001) vs. baseline; global measures showed 77.5% CGI-C and 76.5% PGI-C "much"/"very much" improved. Adverse events included headache (7.5%), urinary tract infection (4.5%), and diarrhea (3.7%); few patients dropped out for adverse events (10.4%). CONCLUSIONS: DM/Q significantly reduced PBA symptoms in patients with dementia; reported adverse events were consistent with the known safety profile of DM/Q. Trial Registration clinicaltrials.gov identifier: NCT01799941.

Clinical Features and Related Factors of Poststroke Pathological Laughing and Crying: A Case-Control Study.

OBJECTIVES: The purpose of this study was to analyze clinical features and related factors of poststroke pathological laughing and crying (PSPLC) and to differentiate PSPLC patients with and without pseudobulbar signs. METHODS: We performed a case-control study in which 56 patients with PSPLC were matched to 56 control stroke patients by age and gender. The pathological laughing and crying scale was used to identify patients with PSPLC. Characteristics of PSPLC outbursts, presence of pseudobulbar signs and autonomic symptoms, lesion locations, and different clinical data were analyzed. Mild cognitive impairment (MCI) was evaluated by the Montreal Cognitive Assessment. Poststroke anger proneness (PSAP) was evaluated by comparison of the patients' premorbid states. RESULTS: Significantly more patients in the PSPLC group showed MCI, PSAP, and pseudobulbar signs than those in the control group. Most patients with PSPLC showed bilateral multiple lesions and the pons (especially the bilateral paramedian basal and basal-tegmental areas) stood out as the most important lesion location. Logistic regression analysis showed that pontine lesion, MCI, and PSAP were independently related to PSPLC; however, the presence of pseudobulbar signs was not related. PSPLC patients with pseudobulbar signs showed more recurrent strokes in the previous 2 years, more severe neurological deficits, as well as higher severity of PSPLC. In addition, more patients in the group with pseudobulbar signs showed concomitant autonomic symptoms. CONCLUSIONS: PSPLC, MCI, and PSAP could be manifestations of a more general disorder, in which pontine lesion plays an important role. PSPLC patients with pseudobulbar signs and those without show different features.

Crying and suicidal, but not depressed. Pseudobulbar affect in multiple sclerosis successfully treated with valproic acid: Case report and literature review.

OBJECTIVE: Pseudobulbar affect/emotional incontinence is a potentially disabling condition characterized by expressions of affect or emotions out of context from the normal emotional basis for those expressions. This condition can result in diagnostic confusion and unrelieved suffering when clinicians interpret the emotional expressions at face value. In addition, the nomenclature, etiology, and treatment for this condition remain unclear in the medical literature. METHOD: We report the case of a 60-year-old woman with multiple sclerosis who was referred to an inpatient psychiatry unit with complaints of worsening depression along with hopelessness, characterized by unrelenting crying. Our investigation showed that her symptoms were caused by pseudobulbar affect/emotional incontinence stemming from multiple sclerosis. RESULTS: The patient's history of multiple sclerosis and the fact that she identified herself as depressed only because of her incessant crying suggested that her symptoms might be due to the multiple sclerosis rather than to a depressive disorder. Magnetic resonance imaging demonstrated a new plaque consistent with multiple sclerosis lateral to her corpus callosum. Her symptoms resolved completely within three days on valproic acid but returned after she was cross-tapered to dextromethorphan plus quinidine, which is the FDA-approved treatment for this condition. SIGNIFICANCE OF RESULTS: This case provides important additional information to the current literature on pseudobulbar affect/emotional incontinence. The existing literature suggests a selective serotonin reuptake inhibitor (SSRI) and dextromethorphan/quinidine (Nuedexta) as first-line treatments; however, our patient was taking an SSRI at the time of presentation without appreciable benefit, and her symptoms responded to valproic acid but not to the dextromethorphan/quinidine. In addition, the case and the literature review suggest that the current nomenclature for this constellation of symptoms can be misleading.

[TRANSIENT PSEUDOBULBAR SYNDROME IN UNILATERAL FRONTAL OPERCULAR INFARCTS]. / ÁTMENETI PSEUDOBULBARIS TÜNETCSOPORT EGYOLDALI FRONTÁLIS OPERCULARIS INFARKTUSOKNÁL.

The classic anterior (frontal) opercular syndrome (Foix-Chavany-Marie sy.) is a cortical pseudobulbar palsy mainly due to bilateral lesions of anterior brain operculum. In 2000 the authors had a 70-year old female patient with acute onset of swallowing and speaking difficulty. Neurological examination established a left facial central palsy, the palsy of the tongue and the soft palate, dysarthry, difficulty in chewing with left side hemiparesis. The CT scan showed a right side (one-sided) frontal opercular ischemic lesion. This event switched their attention especially to this group of cases and subsequently the authors collected 12 patients with these symptoms. Authors discuss the patomechanism of transient pseudobulbar palsy that occurs due to unilateral opercular lesion that the diaschisis effect might explain.

Pseudobulbar paralysis in the Renaissance: Cosimo I de' Medici case.

Cosimo I de' Medici (1519-1574) was the first Grand Duke of Tuscany. He was one of the most important members of the Medici family. He was an excellent conqueror and a good politician. Moreover, he was able to attract and encourage artists, scientists and architects to promote Florence as the cultural capital of the Italian Renaissance. Historical chronicles report that he suffered from a stroke when he was 49 years old. Together with the acute manifestation of stroke, he displayed peculiar symptoms. He had gait disturbances and sphincter dysfunctions. His language became poor and hard to understand. His mood was very fluctuating and in the last years of his life he was a short-tempered man. In addition, he had a characteristic symptom, so-called pathological laughing and crying. The course of his disease was slow and stuttering. Taken together, these data seem to be one of the first reports of pseudobulbar paralysis. The disease of Cosimo I was probably due to a chronic cerebral vasculopathy, known as small vessels disease. We discuss this hypothesis regarding an ancient clinical case, with the support of current studies.

Bilateral perisylvian ulegyria: an under-recognized, surgically remediable epileptic syndrome.

PURPOSE: Interest in the association of epilepsy and pseudobulbar palsy was rekindled since the identification through magnetic resonance imaging (MRI) of bilateral perisylvian polymicrogyria (PMG). Seizures are often intractable, but resective epilepsy surgery has not been recommended. However, a similar clinical picture can be encountered in patients with bilateral perisylvian destructive lesions, which fit the description of ulegyria (ULG). We report a series of patients with epilepsy and pseudobulbar palsy due to bilateral perisylvian ULG (BP-ULG), show that hippocampal sclerosis (HS) is often associated and highlight the fact that in this entity, unlike in malformative bilateral perisylvian PMG, seizures may be surgically treated. METHODS: The motor, cognitive, epileptologic, and imaging features of 12 patients with perisylvian ULG followed at three institutions are described. For patients with refractory seizures, we detail extracranial and intracranial electrographic recordings, surgical strategies, histopathologic analyses of the resected tissue, and outcome of surgical treatment. Descriptive statistics were used for quantitative and categorical variables. Student's t-test was used to compare means, and a p < 0.05 was considered significant. KEY FINDINGS: Pseudobulbar palsy and mental retardation were present in all patients with symmetrical BP-ULG. Five had refractory seizures. There was no relationship between the severity of the pseudobulbar palsy or of the mental retardation and the degree of seizure control with medication. The five patients in whom seizures were refractory to medication had significantly earlier age of onset and longer duration of epilepsy (p < 0.05). Dual pathology with associated unilateral HS was present in four. One patient with dual pathology had a temporolimbic electroclinical picture and had an anterior temporal lobectomy (ATL) based upon noninvasive evaluation. The other four had ictal semiology suggesting involvement of both temporolimbic and perisylvian cortex. Intracranial electroencephalography (EEG) showed concomitant seizure onset in the anterior temporal region and in the ipsilateral ULG in three of the four with dual pathology and in the ulegyric cortex in the one without HS. Resection guided by a combination of semiology, MRI, and extra and intracranial EEG led to complete seizure control in two and almost complete seizure control (Engel class II) in two other patients. The only surgical failure was an isolated ATL in a patient with dual pathology, and concomitant seizure onset in both lesions according to semiology and intracranial EEG. SIGNIFICANCE: Our findings suggest that BP-ULG mimics the clinical features of bilateral perisylvian PMG. In patients with refractory seizures, recognition of this entity should lead to consideration of resective surgery despite the bilateral ULG.

Pseudobulbar dysarthria in the initial stage of motor neuron disease with dementia: a clinicopathological report of two autopsied cases.

We retrospectively analyzed the clinical features of two cases of neurodegenerative disease, whose initial symptoms were motor speech disorder and dementia, brought to autopsy. We compared the distributions of pathological findings with the clinical features. The main symptom of speech disorder was dysarthria, involving low pitch, slow rate, hypernasality and hoarseness. Other than these findings, effortful speech, sound prolongation and initial difficulty were observed. Moreover, repetition of multisyllables was severely impaired compared to monosyllables. Repetition and comprehension of words and sentences were not impaired. Neither atrophy nor fasciculation of the tongue was observed. Both cases showed rapid progression to mutism within a few years. Neuropathologically, frontal lobe degeneration including the precentral gyrus was observed. The bilateral pyramidal tracts also showed severe degeneration. However, the nucleus of the hypoglossal nerve showed only mild degeneration. These findings suggest upper motor neuron dominant motor neuron disease with dementia. We believe the results indicate a subgroup of motor neuron disease with dementia whose initial symptoms involve pseudobulbar palsy and dementia, and which shows rapid progression to mutism.

Behind the screen: pseudobulbar symptoms after deep brain stimulation.

BACKGROUND: Thalamotomy was formerly used to treat different tremor syndromes. Nowadays, deep brain stimulation has become an established technique to treat -different movement disorders. The combination of these two stereotactic interventions is rare. CLINICAL PRESENTATION: We present a patient in which a right-sided tremor -syndrome with an underlying pathology of combined essential tremor and Parkinsonian tremor was successfully treated initially with a left-sided thalamotomy and subsequently with -bilateral deep brain stimulation in the subthalamic nucleus. RESULTS: Deep brain stimulation in the subthalamic nucleus resulted in hemidystonia, pathological laughing and crying, dysarthria and dysphagia, all due to dislocation of the stimulation electrodes contacting the internal capsule. After discontinuation of the high-frequency stimulation these side-effects disappeared, but were then reactivated by an LCD television in stand-by mode. CONCLUSION: In this report we discuss the pathophysiology of pseudobulbar symptoms and pathological laughing and crying in context of thalamotomy and dislocated DBS electrodes. Furthermore, we report on the occurrence that magnetic fields in the household have an impact on deep brain stimulation, even if they are in stand-by mode.

Effect of acupuncture treatment on dysphagia caused by pseudobulbar paralysis after stroke: a systematic review and meta-analysis.

BACKGROUND: The efficacy of acupuncture in the treatment of dysphagia caused by pseudobulbar paralysis after stroke is lack of evidence-based medicine. Our objective was to synthesize the efficacy of acupuncture in treating dysphagia caused by pseudobulbar paralysis after stroke. METHODS: A comprehensive literature search was performed in 9 databases [PubMed, Web of Science, Embase, Cochrane, Chinese BioMedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), WanFang Data, Chinese Science and Technology Periodicals database (VIP), and Open Grey online database] to screen eligible randomized controlled studies that evaluated the effect of acupuncture in dysphagia caused by pseudobulbar paralysis after stroke. The search time limit is from establishing the database to October 1, 2020. The random-effects model was used to calculate the significant effect size. RESULTS: A total of 7 studies comprising 637 participants were included in our meta-analysis. The results showed that compared with rehabilitation, acupuncture had a significant effect on improving dysphagia caused by pseudobulbar paralysis after stroke [the significant effective size: risk ratio (RR)sig =1.51; 95% confidence interval (CI): 1.30-1.75; I2=0%]. In the subgroup analyses, the RRsig of acupuncture + rehabilitation vs. rehabilitation was 1.56 (95% CI: 1.30-1.87; I2=0%), and the RRsig of acupuncture vs. rehabilitation was 1.38 (95% CI: 1.08-1.76; I2=0.8%). DISCUSSION: Acupuncture can be used as an effective treatment for dysphagia caused by pseudobulbar paralysis after stroke. Acupuncture combined with rehabilitation therapy has better effects.

[Acupoint selection rules of acupuncture for pseudobulbar palsy dysphagia].

OBJECTIVE: To analyze the acupoint selection rules of acupuncture for pseudobulbar palsy dysphagia using data mining technology. METHODS: The literature of acupuncture for pseudobulbar palsy dysphagia published from January 1, 1990 to May 1, 2021 was retrieved from CNKI, SinoMed, Wanfang, VIP, and PubMed databases. Acupuncture prescription database was established. The frequency of acupoint selection was analyzed by Microsoft Excel 2016; Apriori algorithm was used to analyze the association rules and draw the high-frequency acupoint co-occurrence network diagram; SPSS21.0 was used to perform clustering analysis. RESULTS: A total of 87 literature was included, involving 89 acupuncture prescriptions and 71 acupoints. Fengchi (GB 20) was the most frequently-used acupoint; the commonly-selected meridians were gallbladder meridian, conception vessel, governor vessel and stomach meridian; the acupoints located at the neck were the most frequently-used acupoints; the crossing points were commonly selected among the special acupoints. The most commonly-used acupoint combination was Jinjin (EX-HN 12) plus Yuye (EX-HN 13). CONCLUSION: The modern acupuncture for pseudobulbar palsy dysphagia usually selects local acupoints, especially the neck acupoints such as Fengchi (GB 20) and Lianquan (CV 23). The acupoints in the front and back are concurrently selected with needles towards the disease location.

The relationship between stress, anxiety, and depression levels and pseudobulbar affect in patients with multiple sclerosis.

BACKGROUND: Pseudobulbar affect (PBA) has recently been added to the list of mental disorders commonly observed in patients with Multiple Sclerosis (MS). The emotional changes experienced by MS patients may be associated with other mental problems and adversely affect disease prognosis. However, there are limited studies in the international and national literature on this subject. AIM: This study aimed to evaluate the relationship between PBA and stress, anxiety, and depression levels in patients with MS. DESIGN: This is a descriptive, relational, and cross-sectional study. METHODS: A total of 442 MS patients followed in the neurology outpatient clinic of a hospital and registered with the MS Society in Turkey participated in this study. Data were collected using a personal information form, the Turkish version of the Center for Neurologic Study-Lability Scale (CNS-LS), and the Depression Anxiety Stress Scale (DASS). RESULTS: In this study, 63.3% of the patients had PBA, 21% had extremely severe depression, 41.6% had extremely severe anxiety, and 24.9% had severe stress. Correlation analysis revealed weak positive correlations between CNS-LS total score and DASS subscale and total scores. Depression, anxiety, and stress levels accounted for 22.5% of the variation in CNS-LS total score. CONCLUSION: The results of this study indicate that a majority of MS patients in Turkey experience PBA, depression, anxiety, and stress, and that PBA is positively associated with depression, anxiety, and stress. IMPACT STATEMENT: This study, indicates that should be increased consultation-liaison psychiatry services in Turkey, and MS patients should benefit from comprehensive psychiatric services.

Occipital Interhemispheric Transtentorial Approach for a Pineal Region Meningioma with Pseudobulbar Palsy.

Meningiomas represent 8%-10% of all pineal region (PR) tumors. When they arise from the falx, tentorium, or tentorial incisura, they are not always considered a true PR tumor, as they do not originate from it but instead only grow toward the region. The true meningioma of PR must be originated from the arachnoid envelope of the pineal gland or from the 2 leaflets of the velum interpositum. In both conditions there are no dural attachments.1,2 Occipital interhemispheric transtentorial and supracerebellar infratentorial are the 2 main approaches for tumors within this region. Aside from the surgeon's preference, the position of the venous system and the direction of the tumor growth guide the approach choice. Endoscope assistance can help reach areas unable to be visualized under the microscope.3-5 We report the case of a 37-year-old female with a large PR meningioma (velum interpositum) presenting with intense dysphagia, dysphonia, and bilateral tongue palsy. Given the affected bilateral upper motor tracts associated with bulbar symptoms, a diagnosis of pseudobulbar palsy was considered.6,7 Preoperative imaging also showed compression of the deep venous system. The patient underwent a total resection of the tumor via an occipital interhemispheric transtentorial approach and exhibited a dramatic recovery of neurologic symptoms after the surgery (Video 1). Postoperative venogram showed restoration of the usual deep venous system pattern, which may be associated with significant neurologic improvement. Careful management of the deep veins is mandatory during the resection of PR meningiomas. The venous system improvement after the surgery may be associated with the dramatic recovery seen in this unique case. The patient consented to publication of her images.

Rapidly progressive atypical parkinsonism associated with frontotemporal lobar degeneration and motor neuron disease.

OBJECTIVE: To report the rare but distinct clinical and neuropathological phenotype of non-familial, rapidly progressive parkinsonism and dementia associated with frontotemporal lobar degeneration with motor neuron disease (FTLD-MND). METHODS: Subjects included two 70-year-old women presenting with rapidly progressive severe postural instability, axial-predominant parkinsonism, oculomotor dysfunction and frontal-predominant dementia with language impairment and pseudobulbar palsy. One had diffuse weakness without signs of lower motor neuron disease. Post-mortem evaluations included immunohistochemistry with antiphospho-TAR DNA-binding protein 43 (TDP-43) and genetic analysis of the TARDBP and PGRN genes. RESULTS: Subjects died within 14 months from symptom onset. TDP-43-positive neuronal intracytoplasmic inclusions were prominent in the primary motor cortex, granule cell layer of the hippocampus, and several cranial and spinal cord nuclei. TDP-43 globular glial inclusions (GGI) were identified in one case. There were no mutations in PGRN or TARDBP genes. CONCLUSIONS: FTLD-MND due to TDP-43-proteinopathy should be considered in patients with rapidly progressive parkinsonism and dementia phenotype, especially when aphasia and/or weakness are also present.
