Beyond sleep: Rest and activity rhythm as a marker of preclinical and mild dementia in older adults with less education.

Background: Although sleep duration and sleep-related breathing disorders were associated with dementia previously, few studies examined the association between circadian rhythm association and cognitive status.

Objective: We aimed to investigate the association of rest and activity rhythm with cognitive performance in older people with cognitive complaints and less education.

Methods: Activity rhythm was evaluated with wrist actigraphy in 109 community-dwelling older people with cognitive complaints without diagnosed dementia.

Bilateral ictal EEG is associated with better memory outcome after hippocampal sclerosis surgery.

Objective: To compare memory outcomes after surgery for unilateral hippocampal sclerosis (HS)-associated epilepsy in patients with unilateral and bilateral ictal electrographic involvement.

Methods: We prospectively evaluated HS patients, aged 18-55 years and IQ ≥70. Left (L) and right (R) surgical groups underwent noninvasive video-EEG monitoring and Wada test.

Development of a word accentuation test for predicting cognitive performance in Portuguese-speaking populations.

The Word Accentuation Test (WAT) has been used to predict premorbid intelligence and cognitive performance in Spanish-speaking populations. It requires participants to read a list of words without the accent marks that indicate the stressed syllable. Label="OBJECTIVE">As Portuguese pronunciation is also strongly based on accent marks, our aim was to develop a Brazilian version of the WAT.

Decision-making profile in older adults: the influence of cognitive impairment, premorbid intelligence and depressive symptoms.

Objective: Decision-making (DM) is a component of executive functioning. DM is essential to make proper decisions regarding important life and health issues. DM can be impaired in cognitive disorders among older adults, but current literature is scarce.
