20. According to the DSM, name 3 of the syptoms that can form the diagnosis of depression (3 points) paul week4 10

 

21. In Alzheimer’s, we see certain pathologies. What are these two pathologies? How does stress impact these pathologies? Thinking along these lines, can you theorize as to why stress may also hasten the onset of Huntington’s disease which is caused by a mutated protein which leads to Huntington tangles?

 

Alzheimer’s Pathology

● Tau proteins play a role in stabilizing the cytoskeletons (cellular skeletons) of neurons

● AD is associated with defective tau proteins which cannot stabilize microtubules

● Phosphorylation is a process where a protein is modified by the attachment of a molecule containing phosphorus atoms

● Tau hyperphosphorylation is a hallmark of AD where tau proteins clump into neurofibrillary tangles (NFTs)

● Amyloid precursor protein (APP) is a type of cell membrane protein concentrated in neuronal synapses

● Amyloid beta (Aβ) is an APP-related peptide (group of amino-acids) whose misfolding and aggregation gives rise to Aβ plaques

     
   
   
 

32. Walk me through what happens in PTSD with regards to brain anatomy. How does PTSD impact the stress response and what are some consequences? Week5 p6

 

33. What may account for the gender difference in the rate of depression diagnosis? (2 points) week4 p13

 

35. Why is loneliness something that we should be concerned about for older adults? (3 points) week6 p22

37. Break down the components of the HPA axis and their function in the biological stress response. Name the primary stress hormone(s) released and their function in the body. What happens to the HPA axis with chronic stress? Bioweek4 p4

 

Cortisol, the primary stress hormone, increases sugars (glucose) in the bloodstream, enhances your brain’s use of glucose and increases the availability of substances that repair tissues. Cortisol also curbs functions that would be nonessential or detrimental in a fight-or-flight situation.

 

40. Define epigenetics in the broadest sense. Describe to me the effects of methylation on the DNA in brief. How does this impact inherited genes? What does stress do to these methylation factors? What kind of events may lead to this kind of epigenetic change and how may that impact the offspring who inherit said epigenetics?

week 3, page 10-13 epigenetics” focuses on how DNA. is regulated to achieve those changes.

3.4DNA Methylation

●  A methyl group is a type of molecule containing the –CH3 group of atoms

 

●  DNA methylation is a process whereby methyl groups are added to DNA, thus changing DNA segment activity without changing the actual DNA sequence

 

●  DNA methylation is a powerful suppressor of gene transcription (the process whereby DNA is transcribed into RNA), which is the first step of protein synthesis

 

●  Abnormal levels of DNA methylation have been implicated in cardiovascular diseases (CVDs) like atherosclerosis, and there is hope that DNA methylation measures could be used as early CVD biomarkers

 

●  There is a global loss of methylation in aging, and twin studies indicate that methylation rates diverge as a result of environmental factors
