Disorders of Aging and Cognition Flashcards
DSM-5 Delirium
Disturbance in attention and orientation to the environment,
Significant cognitive disturbance
Senile plaques
Sphere shaped deposits of beta-amyloid protein - excessive in Alzheimer’s
Neurofibrillary tangles
Twisted protein tangles within neurons - excessive in Alzheimer’s
Why are excessive plaques and tangles dangerous?
Contribute to neuron death > plaques interfere with communication, tangles block transport of molecules
Memory-linked proteins
Glutamate, RNA, ACTH, calcium
Autoimmune theory of Alzheimer’s
Changes in aging braincells trigger an autoimmune response > mistaken attack of the immune system on itself
Biomarkares
Biochemical, molecular, genetic, or structural characteristics that usually accompany Alzheimer’s
Vascular neurocognitive disorder
Blood flow to specific brain areas was cut off, thus damaging them
Frontotemproal neurocognitive disorder (Pick’s)
Affect frontal and temporal lobes
Creuzfeldt-Jakob disease
Body spasms caused by viral infection
