Question

Neuroscience approaches and neuroimaging allow us to do all but which of the following:

Compare cognitively healthy brains to brains of individuals with Alzheimer’s disease

Definitively diagnose Alzheimer’s disease and other dementias

Link measures of performance to measures of brain structure or functioning

Link active brain activity with cognitive behavior

Answer 1

In Alzheimer's disease, damage is widespread, as many neurons stop functioning, lose connections with other neurons, and die. First, it destroys the brain part involved in memory including hippocampus. Later, it affects area in cerebral cortex responsible for language, reasoning and social behaviour.

The beta amyloid proteins collected in between neurons. In Alzheimer's, protein clump together to form a plaque and deposited in between neurons and disrupt cell function.
