neurocognitive disorders Flashcards
cognition
operation of the mind including “the mental faculty of knowing, perceiving, recognizing, conceiving, judging, reasoning, and imagining”
primarily intellectual, perceptual but closely integrated with emotional and spiritual values
attention
ability to maintain focus on persons, tasks, or happenings in the environment
executive functioning
ability to PLAN, make suitable decisions, rely on memory, or respond appropriately to feedback (JUDGMENT)
social recognition
ability to recognize, empathize with the EMOTIONS, thoughts, desires, or intentions of others
neurocognitive disorders
disorders that impair the brain’s ability to carry out normal cognitive functioning; affect the brain’s ability to function intellectually, emotionally, socially, occupationally
interchangeable with “cognitive disorders”
parietal & occipital lobes
attend to stimuli, association with ADLs
temporal lobe
identifies stimuli; perceptual and intellectual
frontal lobe
plans appropriate response; integration of emotions and values
delirium
acute confusion always s/t another condition; syndrome NOT disease
- develops rapidly, fluctuates in intensity, is transient
- disturbance in consciousness and attention
- impairment in cognition
sundown syndrome
symptoms and problem behaviors become more pronounced in evening
may occur in both delirium and dementia
dementia
serious, major neurocognitive disorder with insidious onset compromised of multiple cognitive deficits
- impairment in MEMORY and COGNITION
- WITHOUT impairment in consciousness
60-90% Alzheimer’s
primary dementia
primary encephalopathy
no known cause or cure, progressive and irreversible
80% of dementias irreversible
secondary dementia
reversible components typically s/t pathology
alzheimer’s disease
begins to damage brain long before symptoms appear; affects processes keeping neurons healthy (communication, metabolism, repair)
- tau protein responsible for stability of microtubules
- destruction/death of cells
- anatomical: neurofibrillary tangles, senile plaques, granulovascular degeneration, brain atrophy
beta-amyloid plaques
aka senile plaques; higher amount correlated with degree of mental deterioration in alzheimer’s disease
