Psych Lesson 12 Important Concepts
Acetylcholine (ACh)
Neurotransmitter, pervasive throughout the nervous system, that contributes to movement, attention,
arousal, and memory. A deficiency of acetylcholine is found in people with Alzheimer's disease.
Agnosia
Inability to recognize and name objects; may be a symptom of dementia or other brain disorders.
Amnestic Disorder
Deterioration in the ability to transfer information from short- to long-term memory, in the absence of
other dementia symptoms, as a result of head trauma or drug abuse.
Amyloid Protein
Solid, waxy substance forming the core of the amyloid plaque characteristic of people with Alzheimer's
disease.
Aphasia
Impairment or loss of language skills resulting form brain damage caused by stroke, Alzheimer's disease,
or other illness or trauma.
Apoptosis
(WEB DEF) Necessary death of cells: a form of cell death necessary to make way for new cells and to
remove cells whose DNA has been damaged to the point at which cancerous change is liable to occur.
Bradykinesia
Slowed body movements, as occur in Parkinson's disease.
Chorea

Motor problems characterized by involuntary limb movements.
Creutzfeldt-Jakob Disease
Extremely rare condition that causes dementia.
Delirium
Rabid-onset reduced clarity of consciousness and cognition, with confusion, disorientation, and deficits
in memory and language.
Dementia
Gradual-onset deterioration of brain functioning, involving memory loss, inability to recognize objects or
faces, and problems in planning and abstract reasoning. These are associated with frustration and
discouragement.
Dementia of Alzheimer's Type (DAT)
Gradual-onset of cognitive deficits caused by Alzheimer's disease, principally identified by a person's
inability to recall newly or previously learned material. The most common form of dementia.
Neuritic Plaque
AKA amyloid plaque. Clusters of dead neurons found during autopsy in the brains of people with
Alzheimer's disease.
Neurofibrillary Tangles
Brain damage in the form of large numbers of strand-like filaments found during autopsy in people with
Alzheimer's disease.
Pick's Disease
Rare neurological disorder that results in presenile dementia.
Senile and Presenile

Document Summary
Neurotransmitter, pervasive throughout the nervous system, that contributes to movement, attention, arousal, and memory. A deficiency of acetylcholine is found in people with alzheimer"s disease. Inability to recognize and name objects; may be a symptom of dementia or other brain disorders. Deterioration in the ability to transfer information from short- to long-term memory, in the absence of other dementia symptoms, as a result of head trauma or drug abuse. Solid, waxy substance forming the core of the amyloid plaque characteristic of people with alzheimer"s disease. Impairment or loss of language skills resulting form brain damage caused by stroke, alzheimer"s disease, or other illness or trauma. Apoptosis (web def) necessary death of cells: a form of cell death necessary to make way for new cells and to remove cells whose dna has been damaged to the point at which cancerous change is liable to occur. Slowed body movements, as occur in parkinson"s disease.
