module 7 Flashcards
a neurotransmitter that helps regulate mood, arousal, and cognition.
secreted by the nuclei
-made by brainsterm: Raphe nuclei
serotonin
- regulates mood, arousal, attention, and cognition
-made by Brainstem: locus coeruleus
norepinephrine
-neurotransmitter that regulates mood, arousal, cognition, and motor control
-made by brainstem: substantia nigra
Dopamine
made by the Dopaminergic diffuse modulatory systems arise from the substantia nigra and the ventral tegmental area
helps regulate sleep, arousal, and attention
-made by basal forebrain: basal nucleus of Meynert
acetylcholine (ACh)
The medial septal nuclei and basal nucleus of Meynert project widely upon the cerebral cortex, including the hippocampus.
-Cholinergic diffuse modulatory systems arise from the basal forebrain and brainstem
Low levels of serotonin, norepinephrine, and dopamine have been associated with
Depressive symptoms
Low concentrations of serotonin with high levels of norepinephrine have been associated with
Anxiety symptoms
Too much dopamine with low concentrations of serotonin in certain areas of the brain lead to symptoms of
psychosis and mania
low concentration levels of acetylcholine.2
Dementia
Common risk factors in patients with anxiety and related disorders include
family history of anxiety, personal history of anxiety or mood disorder, childhood stressful life events or trauma, being female, chronic medical illness, and behavioral inhibition.
Obsessions which are repeated and unwanted thoughts that could lead to certain actions or habits (compulsions) could signify
- characterized by intrusive thoughts and ritualistic behavior
obsessive–compulsive disorder.
may include thoughts of hurting someone else, sexual thoughts, excessive concern about contamination/germs/disease, and mental rituals (e.g., counting, praying, repeating).
obsessions
can manifest as repetitive acts of washing, cleaning, checking (e.g., doors, locks, appliances), arranging, and repeating (e.g., counting, touching, praying) as well as hoarding, collecting, and saving.
compulsions
Excessive worry persisting over a 4-week period suggests a possible
generalized anxiety disorder
Hyperthyroidism, cardiopulmonary disorders, and traumatic brain injury (TBI) are common comorbid conditions that accompany
excessive or uncontrollable anxiety
often presents with recurrent sudden episodes/spells/attacks of intense fear or discomfort that are unexpected or with intervening periods of living in fear or worrying of having another attack or facing the consequences of the attack.
panic disorder
anticipatory anxiety in social situations.
social anxiety disorder
Characterized by reexperiencing, avoidance, persistent negative alterations in cognition and mood, and alterations in arousal and reactivity.
ptsd
personal history of a depressive episode, a family history of first-degree family members with depression, personal history of recent stressful life events or significant childhood adversity, chronic and/or disabling medical illness, and female gender.3
most common risk factor for depression
characterized by at least 2 weeks of depressed/irritable mood, with at least four of the following: anhedonia, insomnia or hypersomnia, decreased self-esteem, low energy, poor concentration or indecision, changes in appetite, feeling slowed or restless, and thoughts of death or suicid
Major depressive disorder (MDD)
little interest or pleasure in doing things
(anhedonia
characterized by depressive/irritable mood lasting for at least 2 years with at least two of the aforementioned depressive symptoms
Persistent depressive disorder (PDD)
present with both depressive episodes, such as in major depressive disorder (MDD), as well as manic or hypomanic episodes. Symptoms of manic episodes include euphoric/irritable mood, grandiosity, decreased need for sleep, talkativeness, racing thoughts, distractibility, increased goal-directed behavior or agitation, and an increase in reckless pleasure-seeking (having unprotected sex, spending excess money, foolish investments
bipolar disorder
can be mimicked by medical conditions and substance use. Screening for heart disease, stroke, diabetes, thyroid problems, and alcohol/drug use is crucial to clarifying the diagnosis
-Parkinson disease, traumatic brain injury (TBI), recent myocardial infarction (MI) or stroke, and hypothyroidism may mimic depressive symptoms. Additionally, alcohol use and recent substance use may present in a similar way to depressive symptoms
depressive symptoms
