Study Notes

The Limbic System

Involved in temperature regulation, appetite control, endocrine function, sexual drive, and impulsive behavior associated with feelings of anger, rage, or excitement
Disturbances in the limbic system have been implicated in various mental illnesses, such as dementia and psychotic or manic behavior

Neurotransmitters

Chemical substances manufactured in the neuron that aid in the transmission of information throughout the body
Either excite or stimulate an action in the cells (excitatory) or inhibit or stop an action (inhibitory)
Fit into specific receptor cells embedded in the membrane of the dendrite, like a key fitting into a lock

Psychotropic Drugs

A broad term referring to medications that affect mental function, behavior, and experience
Typically administered to older adults to manage symptoms of anxiety, depression, psychological distress, and/or insomnia
Types: antidepressant, anti-anxiety medications, stimulants, antipsychotics, mood stabilizers
Often decreased gradually (tapering) rather than abruptly to avoid potential problems with rebound, recurrence, or withdrawal

Psychiatric Rehabilitation and Recovery

Refers to services designed to promote the recovery process for clients with mental illness
Goals: recovery from mental illness, personal growth, reintegration into the community, empowerment, increased independence, improved quality of life
Characteristics of Later Recovery: accepting illness, managing symptoms effectively, being actively engaged in the community, having meaningful social contact, coping with family relationships, valuing self and others

Peers and Recovery

Peer counselors and programs have been shown to improve client functioning, satisfaction, self-confidence, and hope for recovery
Peer support can reduce inpatient use and improve many recovery outcomes

Neurotransmitter Acetylcholine

The neurotransmitter at neuromuscular junctions, synapses in the ganglia of the visceral motor system, and various sites within the central nervous system
Derived from its chemical structure: an ester of acetic acid and choline
Regulates cardiac contractions and blood pressure, intestinal peristalsis, glandular secretion, etc.
Activating cholinergic receptors includes muscle contraction, heart rate deceleration, constriction of the iris (miosis) and of the lens, mucus secretion, and bronchoconstriction

Third-Generation Antipsychotics

Stabilize dopamine output, preserving or enhancing dopaminergic transmission when it is too low and reducing it when it is too high
Examples: aripiprazole (Abilify), cariprazine (Vraylar), brexpiprazole (Rexulti)
Used for schizophrenia, manic episodes, and as adjunct medication in bipolar disorder and depression
Common side effects: sedation, weight gain, akathisia, headache, anxiety, and nausea
