• How does reviewing the genetic makeup of a client help guide the PMHNP in
selecting medication for clients? -✓✓-Genetic testing can assist by providing more
information on how clients may respond to certain psychotropic medications
-provides information on how a client may break down and metabolize
medications based on the cytochrome P450 system.
• Tanrıkulu and Erbaş (2020) investigated identical twins to determine the presence
of an inherited link for schizophrenia and why one twin may develop
schizophrenia when the other does not. When two people have 100% identical
DNA, why don't both persons develop the exact illnesses? Studies of identical
Danish twins found that if one twin had schizophrenia, the other twin had a 50%
lifetime risk of developing schizophrenia (Lemvigh et al., 2020). Why is there only
half the risk? -✓✓Both environmental and psychosocial stressors can impact
mental health. Although twins may have identical genes, their gene expression may
be different.
There may be an environmental exposure that turned a gene "on" that should have
been "off" for one twin to develop schizophrenia and not the other.
• central sulcus -✓✓separates the frontal lobe from the parietal lobe
• frontal lobe -✓✓associated with movement, intelligence, abstract thinking
• broca's area -✓✓speech production
,• temporal lobe -✓✓involves object identification and auditory signals
• cerebellum -✓✓coordination
• wernicke's area -✓✓speech comprehension
• occipital lobe -✓✓primary visual area
• parietal lobe -✓✓keeps us alert to what is going on around us
• sensory cortex -✓✓pain, heat, and other sensations
• motor cortex -✓✓movement
• hippocampus -✓✓involved in both memory and anxiety
• nucleus accumbens -✓✓involved in the reward process
• thalamus -✓✓involved in sensory organ and motor command processing
• striatum -✓✓involved in complex motor actions, also links cognition to motor
actions
,• limbic system -✓✓includes circuits that are associated with pleasure and reward
• basal ganglia -✓✓group of structures involved in voluntary motor movements
• amygdala -✓✓involved in emotional regulation and perception of odors
• corpus callosum -✓✓controls the communication between the two brain
hemispheres
• white matter -✓✓contains nerve fibers that connect neurons from different
regions into functional circuits
• grey matter -✓✓contains nerve cells and dendrites
• brain tissue -✓✓made up of grey matter and white matter
• dorsal striatum -✓✓involved in complex motor actions and linkage of cognition
to motor actions
-main input area for basal ganglia
*activated when anticipating or engaging in pleasure
• The field of epigenetics is rapidly growing and can help explain how gene
expression is: -✓✓influenced by environmental factors and how epigenetics
contributes to the manifestation of mental illness
, • How does epigenetics impact a person's mental health? -✓✓internal or external
factors activate portions of the genome that result in the manifestation of mental
health symptoms
-activation is often a result of a stressful event, which, when combined with the
genetic risk, results in the disease
-genes being on or off
-occurrence of symptoms may be the result of inheritance of an abnormal gene or
of normal genes being "on" when they should be "off."
• Types of epigenetic changes: -✓✓DNA Methylation
Histone modification
Non-coding RNA
• The potential legal and ethical issues impacting mental health treatment must also
be taken into account, including: -✓✓-informed consent
-competence to make healthcare decisions
-off-label prescribing
• Informed consent -✓✓Clients have the right to receive enough information to
make decisions about treatment.
-must also be informed about potential risks associated with medications.
-have the right to refuse treatment
-cannot be forcibly medicated in non-emergencies. However, clients can be
forcibly medicated if they are violent toward themselves or others and when less
restrictive methods have failed
• Compliance -✓✓A court order may be issued for a client to receive treatment
against their wishes if they are considered a danger to themselves or others.
