[The contribution of nuclear medicine procedures in the diagnosis of dementia of Alzheimer's type. Imaging beta amyloid plaques].

Pathogenesis of dementia of Alzheimer's type (DAT) is unknown. Progressive deposition of beta-amyloid plaques (beta-AlphaPs) is one of the major pathological features of DAT and precedes cognitive decline in these patients. Noninvasive detection of beta-AlphaPs could, therefore, may be a potential diagnostic test for the early detection of DAT patients.

Neuropsychological EEG activation in patients with juvenile myoclonic epilepsy.

We studied the effects of higher mental activity on the EEG, i.e., neuropsychological EEG activation (NPA), in patients with juvenile myoclonic epilepsy (JME).

Greek validation of the seven-minute screening battery for Alzheimer's disease in the elderly.

The increasing prevalence ofAlzheimer's disease (AD) suggests that there is an increasing need for accurate and easily administered screening instruments. The Seven-Minute Screen is a neurocognitive screening battery consisting of four brief tests (enhanced cued recall, temporal orientation, verbal fluency, and clock drawing). We studied 55 outpatients with probable AD, 40 healthy volunteers of comparable age, sex, and education and 31 elderly patients with other neuropsychological disorders.
