Do antipsychotics cause permanent or long term changes in brain structure or chemistry? Feel like I lost a lot of my old self and I can't get it back

Do antipsychotics cause permanent or long term changes in brain structure or chemistry? Feel like I lost a lot of my old self and I can't get it back

Maybe, maybe not: The effect depends on the antipsychotic. Sometimes the changes are beneficial. The changes that you are seeing in yourself could be due to medication but could also be due to the condition that the antipsychotic is treating. It is important to discuss these concerns with your physician and not assume that it is the medication causing the problem. ...Read more

What is the difference in brain structure of someone with a memory loss disorder?

It depends: It really depends on the reason for the memory loss. Different pathologies have different brain structure changes. And some people with the same diagnosis (i.e., vascular dementia) might have different areas of their brain affected. ...Read more

Whats the brain structure like for a person with normal memory loss vs a memory loss disorder?

Whats the brain structure like for a person with normal memory loss vs a memory loss disorder?

Atrophy: Various areas of the brain will shrink, or atrophy, with progressive memory disorders, and the patterns can assist with clinical diagnosis. Although normal aging is associated with gradual atrophy, this is far less than alzheimer's. Atrophy, either focal or diffuse, can be present in younger patients following a brain injury, or multiple sclerosis. ...Read more

Is it true that methylphenidate can cause changes in the brain like neurons structure after long term use (years)?

Is it true that methylphenidate can cause changes in the brain like neurons structure after long term use (years)?

Not in monkeys: There is no data yet that convincingly show long-term problems with methylphenidate. In fact one study done in monkeys specifically showed no change in brain structure on pet scan. The ultimate study of course remains to be done on humans. I think that it's safe to say that the basic science research looks very good but the final studies in human beings still need to be carried out. So far however there was no signal that long-term structural changes are occurring. Hopefully will find this reassuring and helpful. Best wishes. ...Read more

Can depression and ptsd change your brain structure and cause neurological problems later in life? I am 33 and have been on meds & therapy for 5 yrs.

Can depression and ptsd change your brain structure and cause neurological problems later in life? I am 33 and have been on meds & therapy for 5 yrs.

Brain changes: Ptsd can cause significant changes in brain physiology. The amygdala (fight or flight) becomes over -active. The frontal cortex forgets to monitor the amygdala- so there is more impulsive behavior the hippocampus forgets to do it's job laying down new memories and retrieving old ones. Neurotransmitters are out of wack. Early and aggressive treatment is important for optimal outcomes in tx. ...Read more

Did you learn any useful methods in med school for remembering the structure, function, and location of different tissue types?

Did you learn any useful methods in med school for remembering the structure, function, and location of different tissue types?

Yes: Medical school includes courses in anatomy physiology, and histology. You are actively dissecting bodies, reviewing microscopic slides of tissues, learning muscle and organ actions, and studying medical biochemistry in the curriculum. These courses are usually among the first most medical students take, and they often run simultaneously. ...Read more
