Parkinson's Disease With Visual Hallucinations Is Associated With Epileptiform Activity on EEG.

Background: Visual hallucinations (VHs) in Parkinson's disease (PD) are the cardinal symptoms which declare the onset of PD psychosis (PDP). The anthropomorphic and zoomorphic VHs of PD resemble those of Charles Bonnet syndrome and temporal lobe epilepsy. In both of these disorders electroencephalography (EEG) abnormalities have been described. We therefore sought to examine whether VHs in PD were associated with similar EEG abnormalities. Methods: This retrospective observational study searched the medical records of 300 PD patients and filtered for those containing clinical 20-min scalp EEGs. Remaining records were separated into two groups: patients with reported VHs and those without. The prevalence of epileptiform discharges in the EEGs of both groups was identified. Results: Epileptiform discharges were present in 5 of 13 (38.5%) PD patients with VHs; all localized to the temporal lobe. No epileptiform discharges were observed in the EEGs of the 31 PD patients without VHs. Conclusion: The significantly high incidence of temporal lobe epileptiform discharges in PD patients with VHs as compared to those without VHs lends to the possibility of an association visual cortex epileptogenic focus. Accordingly, for treatment-refractory patients, antiepileptic drugs might be considered, as in the case of Charles Bonnet syndrome, temporal lobe epilepsy and migraine with visual aura. Future prospective studies involving larger samples and multi-center cohorts are required to validate these observational findings.

Cervical Spine Ischemic Stroke Complicated by Spastic Quadriparesis and Ogilvie Syndrome: A Case Report and Literature Review.

Infarction or ischemia of the spinal cord is a rare entity and is often misdiagnosed as inflammatory myelopathy in acute settings. Atherosclerotic disease can affect spinal arteries, leading to cord ischemia with clinical presentation mixed with myelopathy. We present a case of a 66-year-old male who came to the hospital with unsteady gait and numbness of all extremities without associated pain for the past 48 hours. The neurological examination on admission directed the diagnosis towards myelopathy of the cervical spine. However, the initial magnetic resonance imaging (MRI) of the cervical spine demonstrated gliosis and restricted diffusion of the cord with multilevel neuroforaminal stenosis but without central canal stenosis or cord compression. The MRI brain, cerebrospinal fluid analysis, and rheumatologic evaluation were unremarkable. Four days into the clinical course, the patient developed weakness and spasticity of all extremities prompting further evaluation. Computed tomography angiography (CTA) scan of the head and neck revealed right vertebral artery occlusion and intracranial atherosclerotic disease. He was started on aspirin and clopidogrel for secondary risk reduction. The hospital course was further complicated by Ogilvie syndrome (OS), and the patient underwent uncomplicated cecostomy.

Evaluating the utility of fasting lipid panel in addition to random lipid panel in determining lipid-lowering therapy in acute ischemic stroke or TIA patients.

BACKGROUND: Hyperlipidemia is one of the major risk factors for cerebrovascular disease and it is common practice to obtain fasting lipid profile prior to starting lipid lowering therapy (LLT). Recent AHA Guidelines published in 2018 allow for a non-fasting value to be used. OBJECTIVE: To determine if obtaining fasting lipid levels in addition to random lipid levels prompts changes in hyperlipidemia management of acute stroke patients. METHODS: 206 patients met the study criteria which included a diagnosis of acute ischemic stroke or transient ischemic attack on admission and availability of both random and fasting LDL levels collected within 72 h of each other. Patients were divided into three groups based on random LDL at admission: Group A: LDL < 70, Group B: LDL 70-99, and Group C: LDL ≥ 100 mg/dL. The dataset was analyzed to conform to the 2018 AHA/ACC guidelines using an LDL cutoff of 70 mg/dL. RESULTS: In 206 patients, statin management would change based on the fasting LDL level in 12 patients, 11 of whom were in Group B. Our data suggests that lipid management is more likely to change if the initial random LDL falls between 70-99 mg/dL as compared to a value outside of this range (P < 0.001). We present a decision algorithm to guide lipid management in acute stroke patients. CONCLUSIONS: Foregoing a fasting lipid panel to guide LLT in patients with ischemic stroke is appropriate in most cases but for select patients with random LDL levels between 70 and 99, fasting lipid profile should be obtained prior to deciding upon LLT.

Developmental vascular anomaly associated hemi facial spasms and botox injections therapy.

Hemifacial spasm (HFS) is characterized by involuntary synchronous contractions or spasms of one side of the face, usually beginning around the eye. They are typically brief, irregular clonic movements but are occasionally tonic. We present a case of a 41-year-old female who presented to the neurology clinic with complaints of recurrent right facial spasms. These involuntary spontaneous movements had affected her quality of life. The neuroimaging revealed the vascular malformation right cranial nerves (CN) VII/VIII complex. It was considered to be responsible for the patient's HFSs. The patient responded well symptomatically to the botox injections without any neurovascular decompression.
