UTMB ADVANCED PATHOPHYSIOLOGY 5355 Exam 3 WELL SOLVED Biogenic Amine Theory linked to depression ANS-Deficiency of neurotransmitters in brain of norepinephrine, dopamine, and/or serotonin. Particularly, a decrease in receptor binding with serotonin. Neurotransmitter Receptor Hypothesis linked to depression ANS-A deficiency of monoamine neurotransmitters at neuronal synapses. Antidepressants increase ANS-Neuronal synaptic levels of monoamine neurotransmitters. if you have more receptors than neurotransmitters ANS-Neurotransmitters do not have time to re-charge thus, they do not function properly. Hypothalamic-Pituitary-Adrenal (HPA) System Dysregulation ANS-HPA system dysregulation with excessive glucocorticoid secretion is found in a large percentage of people suffering from major depression. Patho of Alzheimer's includes - plaque formation, presence of --, with decreased levels of - ANS-Amyloid B, neurofibrillary tangles, acetylcholine these disrupt impulse transmission neurofibrillary tangles ANS-are a deformation of the structure that carries nutrients to neurons of the brain. Decreased levels of choline acetyl transferase and acetylcholine is associated with ANS-Memory loss Most common cause of dementia ANS-Alzheimer's disease fatal 5-10 years Characteristics of Alzheimer's ANS-Loss of memory, language , inability to learn new things, dysfunction, delusions, cannot perform ADLs, majorly effects social life Parkinson's Disease is ANS-Chronic motor progressive neuro-degenerative known as a sh
