What does grey matter consist of?
Correct Answer: Cerebellum, cerebrum, brainstem, and butterfly-shaped portion of the central
spinal cord.
1. Grey matter contains neuronal cell bodies, dendrites, and unmyelinated axons. Associated with
learning; changes linked to Alzheimer's, schizophrenia, MDD.
2. White matter: nerve fibers (axons) that connect neurons from different regions into functional circuits
(transit system). Associated with sensory/motor function and cognition; changes linked to autism and
vascular dementia.
Frontal lobe – function and injury effects
Correct Answer: Movement, intelligence, abstract thinking, ability to organize, personality, behavior,
emotion control. Injury causes personality changes, difficulty controlling emotion.
1. Prefrontal cortex: executive function. Thalamus: motor command processing.
, Amygdala, hippocampus, Wernicke's area, Broca's area functions
Correct Answer: Amygdala: anxiety/fear, perception of odors. Hippocampus: long-term memory,
anxiety. Wernicke's area: speech comprehension. Broca's area: speech production.
1. Basal ganglia: voluntary motor movements, cognition, emotion. Limbic system: emotion and learning.
2. Parietal lobe: somatic senses. Temporal lobe: contains limbic system, amygdala, hippocampus;
disorders include ADHD, dementia. Occipital lobe: visual processing (seizures here cause hallucinations
such as lines of color).
When could the client's cognitive status create an ethical issue?
Correct Answer: If the client is unable to self-determine care or is a danger to self or others.
1. Informed consent: clients have right to receive enough information to make treatment decisions, be
informed of medication risks, right to refuse treatment (cannot be forcibly medicated in non-
emergencies). Exceptions: danger to self/others and less restrictive methods failed.
2. Compliance: a client may be court-ordered to receive treatment against their will if danger to self or
others. Examples: schizophrenia, sex offenders. Guardians can provide consent if client lacks cognitive
function.
Epigenetics definition and importance in mental health
Correct Answer: Study of how behaviors and environment cause changes that affect the way genes
work (without DNA sequence change). Activation of a gene is often caused by a stressful event.
Increased risk for psychiatric disease when stressful event combined with genetic risk.
1. Epigenetic changes are reversible (they change the way body reads DNA sequence, not the sequence
itself). Transcription factors are proteins that bind to promoter sequences of DNA to turn gene expression
on/off.
2. Epigenetic changes can be influenced by infections, cancer, nutrition during pregnancy.
How is genetic testing useful in psychiatry?
Correct Answer: Provides information on how clients might respond to certain psychotropic
medications by providing info on how a client metabolizes a drug based on the CYP450 system.
1. Incidence of mental health: 30% of world suffering from neurologic or psychiatric disorder; 20% of
children and adolescents affected.
2. Client factors affecting adherence: side effects, fear of addiction, misunderstanding of expected
outcomes. Clinician factors: lack of shared decision making, inadequate education, lack of follow-up.
Structural factors: medication access, costs, stigma.
CYP450 phase 1 metabolism and outcomes
Correct Answer: Drug is ingested orally → oxidation (most common), reduction, or hydrolysis.
Three outcomes: 1) drug becomes completely inactive; 2) drug becomes partially inactive (one+
metabolites remain active); 3) original drug not pharmacologically active but metabolite remains
active.
1. CYP450 enzymes in gut wall or liver convert drug substrate into biotransformed product in
bloodstream.
2. Genetics: variations in genes encoding CYP450 enzymes alter enzyme activity → alterations of drug
levels at standard doses.
