What is the biogenic amine theory related to depression? - (answer)It suggests a deficiency of
neurotransmitters in the brain, primarily norepinephrine, serotonin, and dopamine.
What happens to neurotransmitter receptors in depression? - (answer)There is a decrease in
receptor binding with serotonin and an up-regulation of some post-synaptic receptors due to
neurotransmitter deficiency.
What is the neurotransmitter receptor hypothesis? - (answer)It refers to decreased levels of
monoamine neurotransmitters at neuronal synapses, leading to depressive symptoms.
How do antidepressants affect neurotransmitters? - (answer)Antidepressants increase neuronal
synaptic levels of monoamine neurotransmitters, facilitating communication between neurons.
What is major depression? - (answer)A mood disorder characterized by a depressed mood, loss
of interest, feelings of guilt, fatigue, and changes in sleep and appetite.
,What is the difference between Bipolar I and Bipolar II disorders? - (answer)Bipolar I involves at
least one manic episode, while Bipolar II includes at least one depressive episode and one
hypomanic episode.
What role do proinflammatory cytokines play in depression? - (answer)They increase in blood
during depression and may contribute to neuroinflammation, worsening depressive symptoms.
What is the hypothalamic-pituitary-adrenal (HPA) system's role in depression? -
(answer)Dysregulation of the HPA system leads to excessive cortisol secretion, which is found in
a significant percentage of people with major depression.
What is the significance of choline acetyl transferase in Alzheimer's disease? -
(answer)Decreased activity of this enzyme, responsible for producing acetylcholine, is associated
with memory impairment in Alzheimer's patients.
What are neurofibrillary tangles and senile plaques? - (answer)They are deposits found in the
cerebral cortex of Alzheimer's patients, associated with neuronal cell loss and memory
impairment.
,What is amyloid beta protein's role in Alzheimer's disease? - (answer)Increased production or
deposition of amyloid beta protein is thought to contribute to neurodegeneration and may disturb
calcium homeostasis.
What is the relationship between calcium homeostasis and neurotransmitter release? -
(answer)Calcium is essential for neurotransmitter release; disturbances can lead to cell death.
What are the two forms of Alzheimer's disease? - (answer)Familial and sporadic, with identical
pathology characterized by decreased acetylcholine production and neuronal loss.
How does the frontal lobe contribute to memory? - (answer)It organizes and classifies
information necessary for memory formation.
What is the role of the hippocampus in memory? - (answer)It creates and coordinates memories
of tangible facts and events, retrieving information stored in the cerebral cortex.
What is the impact of omega-3 fatty acids on depression? - (answer)They may help regulate
inflammation and improve depressive symptoms.
, What is the significance of genetic and environmental influences on mood disorders? -
(answer)There is a familial tendency for developing mood disorders, with adoptees in affected
families showing higher incidence rates.
What is the effect of antidepressants on HPA system dysregulation? - (answer)Antidepressants
that normalize the HPA system are associated with better outcomes in treating depression.
What is the relationship between oxidative metabolism and amyloid fibrils in Alzheimer's? -
(answer)Changes in oxidative metabolism may lead to a buildup of amyloid fibrils, which could
explain the effectiveness of antioxidants.
What is the role of inflammation in amyloid fibril toxicity? - (answer)An inflammatory
component may be involved in the toxicity of amyloid fibrils, suggesting that anti-inflammatory
drugs could be beneficial.
What are the major symptoms of depression? - (answer)Symptoms include depressed mood, loss
of interest, feelings of guilt, fatigue, and changes in sleep and appetite.
What is the difference between unipolar depression and bipolar disorder? - (answer)Unipolar
depression involves only depressive episodes, while bipolar disorder includes both depressive
and manic episodes.
