RESUMO
This exploratory study investigated meaning in life (MiL) in patients with progressive supranuclear palsy (PSP). In the "Schedule for Meaning in Life Evaluation" (SMiLE), respondents list individual MiL areas before rating their current satisfaction and importance with them (index of weighting [IoW], index of satisfaction [IoS], and index of weighted satisfaction [IoWS], range 0-100). A total of 38 patients with PSP completed the SMiLE (IoS: 68.6 ± 25.6, IoW: 79.6 ± 12.6, and IoWS: 69.2 ± 26.1). A representative sample of healthy participants (n = 977) scored significantly higher in the IoS (82.8 ± 14.7, P < .001), the IoW (85.6 ± 12.3, P = .006), and the IoWS (83.3 ± 14.8, P < .001). Compared to healthy individuals, patients with PSP were less likely to list health (P = .001) and more likely to list partner (P = .04), leisure (P = .01), home/garden (P = .01), and pleasure (P = .02). Patients with PSP seem to focus on supportive relationships and leisure, while the decreasing health status is becoming less important to them.

Some previous studies in brain-damaged patients suggested that neural systems in the left temporal lobe might be crucial in the production and comprehension of nouns, while analogous systems in posterior frontal cortical areas might be involved in the production and comprehension of verbs. We assessed performance on neuropsychological tasks of production and comprehension of nouns and action-verbs in 10 patients with progressive supranuclear palsy (PSP) and in 10 age-matched healthy controls. PSP patients also underwent measurements of regional cerebral blood flow by means of single photon emission computed tomography (SPECT), using 99mTc-Ethyl Cysteinate Dimer. In all PSP patients, SPECT showed a significant hypoperfusion in the inferior frontal gyrus (IFG). PSP patients performed significantly worse than controls on all lexical-semantic tasks, except for the auditory lexical decision task on nouns. Within PSP patients, however, a significantly lower performance was observed on action-verbs as compared to nouns on various lexical-semantic tasks (oral and written confrontation naming, auditory and visual single-word comprehension). Analysis of individual performance revealed heterogeneous patterns of neuropsychological impairment in different PSP patients. Despite some difficulty in drawing clear-cut conclusions about the locus of functional damage, we hypothesise that in most of our PSP patients such selective impairment in the production and in the comprehension of action-verbs could be due to semantic deficits affecting the conceptual category of actions. These findings are consistent with the hypothesis that in PSP a dysfunction of neural systems in posterior frontal cortical areas (mainly involving the IFG) critical for processing the conceptual category of actions might result in a selective impairment of production and comprehension of action-verbs.

HISTORY AND ADMISSION FINDINGS: A 65-year-old female patient presented with increasing vertigo, tendency to fall, dry cough and, in addition, numerous psychic and somatic symptoms since 6 years. Former diagnostic attempts did not yield clarifying results. In part, the patient had not followed up on former recommendations for further diagnostic procedures. With a suspected somatization disorder the patient was admitted to the Department of Psychosomatic Medicine. INVESTIGATIONS: The neurological examination at admission revealed vertical oculomotor palsy and tendency to fall backwards indicating an affection of the brain stem. A magnetic resonance imaging of the head showed atrophy of the mesencephalon. DIAGNOSIS AND TREATMENT: In light of these findings the patient was diagnosed Steele-Richardson-Olszewksi syndrome. The therapy which comprises training measures and medication with a cholinesterase inhibitor aims to retain neuropsychological and motional abilities. Besides, psychotherapy is offered alongside to help the patient to cope with the disease. CONCLUSIONS: Treating patients with somatic and psychological symptoms calls for careful anamnestic exploration and clinical examination. Psychological alterations following neurological affection of the brain can imitate somatization disorder.

AIMS: To describe obsessive-compulsive symptoms (OCS) as under-recognized behavioral and psychological symptoms of dementia of progressive supranuclear palsy (PSP) and to discuss possible mechanisms based on MRI and SPECT findings. METHODS: We studied 74 PSP patients. OCS are defined as persistent and unreasonable, but non-delusional/hallucinatory, ideas and behaviors. Demography, cognition, the widths of middle cerebellar peduncles (MCP) and the inter-caudate distances (ICD), both corrected by the intracranial size (MCP and ICD ratios), and changes on voxel-based SPECT were compared between the subgroups with and without OCS. Finally, the predicative power of various factors to OCS was investigated. RESULTS: We observed OCS in 18 patients (24%). They were obsessed with daily trifles and physical symptoms among other things. OCS was not associated with demography or cognitive levels. OCS-positive patients had significantly smaller MCP and ICD ratios and showed marked uptake decreases in the orbitofrontal cortex, caudate and thalamus. Relative uptake increases in the cerebellum, specifically the tonsils, were milder in OCS-positive than -negative patients. A smaller right MCP, a smaller ICD ratio and lower uptake increases in the right cerebellar were the significant predictors of OCS. CONCLUSIONS: OCS are frequent but under-recognized behavioral and psychological symptoms of dementia in PSP. Dysfunction of the fronto-caudate-thalamus-cerebellum circuit may be involved.

OBJECTIVE: To study the use of brain parenchyma sonography (BPS) in discriminating between patients with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP). METHODS: Thirteen patients with PSP and eight with CBD were studied with BPS according to a standardized protocol. RESULTS: Seven (88%) of the eight CBD patients showed marked hyperechogenicity of the substantia nigra (SN) but none of eleven PSP patients (Mann-Whitney U test, p < 0.001). This finding indicated CBD with a positive predictive value of 100%. Marked dilatation of the third ventricle (width > 10 mm) was found in 10 (83%) of 12 PSP patients, but in none of the CBD patients (p < 0.005). BPS measurements of ventricle widths closely matched MRI measurements (Pearson correlation, r = 0.90, p < 0.001). The presence of at least one of the BPS findings 1) marked SN hyperechogenicity and 2) third-ventricle width < 10 mm indicated CBD with a sensitivity of 100%, a specificity of 83%, and a positive predictive value of 80%. Other BPS findings such as echogenicity of lentiform and caudate nuclei and widths of the frontal horns did not discriminate between CBD and PSP. One PSP patient could not be assessed because of insufficient acoustic temporal bone windows. CONCLUSIONS: Substantia nigra hyperechogenicity, reported earlier as characteristic brain parenchyma sonography finding in idiopathic Parkinson disease, is also typical for corticobasal degeneration.

The paper reports the results of recordings and maps of event-related potentials (ERPs) in patients with Alzheimer's disease (AD), progressive supranuclear palsy (PSP) and in subjects affected by dementia in multiple sclerosis (MS). ERPs were recorded from 19 scalp electrode derivations using both visual and acoustic paradigms. In 43% of AD patients, ERPs were normal; in 20%, although present, ERP components were delayed, while in the other 37% none of the N2 and P3 peaks could be recorded, because of abnormal topography of potentials on the scalp. In patients with PSP, the normal ERP sequence was not identified. In patients with MS delayed ERPs (50%), abnormal topography of ERPs (30%) and absence of ERPs (20%) were observed. The follow-up of AD patients showed a progressive alteration of ERPs. ERP topography alterations were observed in AD, PSP and MS patients with poorest cognitive performances.

An autopsy case of progressive supranuclear palsy with onset at age 53 and a clinical course of 7 years is reported. The clinico-pathological characteristics of the case were as follows: Fibrillary gliosis of the midbrain and pontine reticular formation corresponded clinically to personality changes: The patient had formerly been irascible and became extremely mild-mannered. He showed lack of spontaneity and initiative and slowing of thought processes, taking him longer than normal to find words and ideas. Gliosis of the nucleus ventralis lateralis of the thalamus was secondary to the degeneration of the cerebellar dentate nucleus and the globus pallidus from which they receive fibers. Neurofibrillary tangles were found in the cerebral cortex.
