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
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
Which brain structure receives information from all of the senses except that of the olfactory nerve?
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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
Not in 400 chars: Not in 400 characters. In biology, you can't separate structure from function. If you want to find out how the brain works, you can start with one of the standard references: Principles of Neural Science, by Kandel and Schwartz. I have the 5th edition, 1709 pages. It covers the basics. It's an introduction. If you want to get deeper into the subject, there are more and bigger books you can read. ...Read more
Intelligent design: The fluid carried by the blood stream/arteries leaks out into the tissues through the capillary walls and when the tissues are healthy, are drawn into the minute lymph channels and flows back into the blood stream at the superior vena cava just above the heart before the blood goes through the lungs for re-oxygenation. Impairment of the delicate channels or lymph nodes results in edema. ...Read moreSee 1 more doctor answer
