Cognitive, functional and behavioral assessment: Alzheimer's disease

Cognitive, functional and behavioral assessment: Alzheimer’s disease

A review of the evidence on cognitive, functional and behavioral assessment for the diagnosis of dementia due to Alzheimer's disease (AD) is presented with revision and broadening of the recommendations on the use of tests and batteries in Brazil for the diagnosis of dementia due to AD. A systematic review of the literature (MEDLINE, LILACS and SCIELO database) was carried out by a panel of exp...

Orbitofrontal Dysfunction Discriminates Behavioral Variant Frontotemporal Dementia from Alzheimers Disease

Background: Behavioral variant frontotemporal dementia (bvFTD) patients show prefrontal cortex dysfunction and atrophy. Methods: We investigated whether executive function in conjunction with prefrontal cortex atrophy discriminates bvFTD and Alzheimer’s disease (AD) patients efficiently at presentation. Results: AD and bvFTD patients were distinguishable by 89.5% on their performance of 3 execu...

Magnesium and Alzheimers Disease: The Cholinergic Hypothesis

The cholinergic deficit in Alzheimer’s disease (AD) remains the cornerstone for the understanding of chemical signal transfer. Hypofunctions of cholinergic systems are significantly involved in the signs and symptoms of senile dementia of the Alzheimer type. Cognitive deficits in AD have been widely associated with dysfunction of the cholinergic system. As a diagnostic marker of AD the activity...

Cognitive Impairments in Siblings of Alzheimers Disease Patients: Possible Preclinical Signs of the Disease

Specific Agonists and Antagonists of Serotonergic Receptors in the Treatment of Cognitive Symptoms in Alzheimers Disease

In Alzheimer’s disease, decreasing activity of acetylcholine and GABA in the hippocampus and prefrontal cortex are combined with cognitive deficits and with the formation of beta-amyloid. Neurotransmitter alterations in these brain regions are described, while a neurotransmitter imbalance with hypoactivity of muscarinic cholinergic, serotonergic and GABAergic neurons and hyperactivity of noradr...
