Neuropsychological Evaluation and Quantitative EEG in Patients with Frontotemporal Dementia, Alzheimer's Disease, and Mild Cognitive Impairment.

This study analyzed the efficacy of EEG resting state and neuropsychological performances in discriminating patients with different forms of dementia, or mild cognitive impairment (MCI), compared with control subjects. Forty-four patients with dementia (nineteen patients with AD, and seven with FTD), eighteen with MCI, and nineteen healthy subjects, matched for age and gender, underwent an extensive neuropsychological test battery and an EEG resting state recording. Results showed greater theta activation in posterior areas in the Alzheimer's disease (AD) and Fronto-Temporal Dementia (FTD) groups compared with the MCI and control groups.

Recurrent status epilepticus as the main feature of Hashimoto's encephalopathy.

Hashimoto's encephalopathy (HE) is a severe but treatable condition that rarely complicates Hashimoto's thyroiditis. Clinically it is characterized by progressive or relapsing symptoms, including tremor, myoclonus, stroke-like episodes, seizures, impairment of consciousness, and dementia. We describe a patient presenting with recurrent generalized convulsive status epilepticus (GCSE), despite antiepileptic medications, who was successfully treated with methylprednisolone.
