Exam 2 SG Flashcards
Disorders or illnesses that are caused by neurotransmitter malfunction
Dopamine - increase - Schizophrenia Serotonin - decreased - Depression Norepinephrine - decrease - Depression y-Aminobutyric acid (Glutamate )- decrease - Anxiety disorders Acetylcholine - decrease - Alzheimers
Function of Broca’s area (Assessment)
Broca’s area is responsible for speech.
Patients with damaged broca’s area has difficulty understanding syntactically complex or semantically reversible sentences (e.g., “touch your nose after you touch your foot”).
Mechanism of action for antipsycotics
Many drugs, such the older neuroleptic antipsychotics, interact with ACh and its receptor sites to produce anticholinergic side effects, which occur when muscarinic acetylcholine receptors are blocked. 1st generation ( typical ) antipsychotics - blocks D2 receptors - not selective 2nd generation (atypical) antipsychotics - blocks D2 and 5HT2A receptor (dopamine and serotonin ) - somewhat selective
1st generation (typical) antipsychotic: mechanism of action
blocks D2 receptors - not selective
2nd generation (atypical) antipsychotic: Mechanism of action
blocks D2 and 5HT2A receptor (dopamine and serotonin ) - somewhat selective
Effects of GABA
brain’s principal inhibitory neurotransmitter
Turns off nerve cells and slows or stops actions in postsynaptic neurons.
Education about donepezil (Aricept)
Donepezil (Aricept) and other similar drugs inhibit the cholinesterase enzyme that breaks down ACh. This increases the amount of available ACh, thereby delaying the onset of symptom
Risk factors for mental illness
Genetics
Assessment for patient with injury to temporal lobe
Auditory hallucinations Increased sexual focus Decreased motivation Alterations in memory Altered emotional responses Sensory aphasia Affect fluctuates dramatically
Behavioral changes related to frontal lobe injury
Changes in affect, such as flattening Alteration in language production Alteration in motor functioning Impulsive behavior Impaired decision making Concrete thinking
Behavioral changes related to PTSD
pt may experience intense fear, helplessness, or horror
pt can be agitated or behave in disorganized manner.
Pt can have sleep disturbances, irritability or angry outbursts, difficulty concentrating, hypervigilance, and an exaggerated startle response
