On different types of antidepressants n tranquillisers for 8 years. will these drugs cause brain damage, dementia or alzheimer's when taken long term?

Long term med effect: Psychiatric medications have not been found to lead to dementia processes (alzheimers or other dementias) or to cause brain damage, unless taken in excess (such as an overdose). Some psychiatric medications have been found to help prevent nerve damage associates with age (lithium) or with anxiety and depression (ssri meds). If you are having any concerning symptoms, seek medical evaluation.

No: Even when taken for many years, these medications do not usually cause brain damate or alzheimer's disease. If you continue to be concerned, speak with you prescribing doctor.

Do not cause, but: Although these meds do not damage brain nerve cells even long-term, there is another issue if one develops a dementia or even alzheimer's. You see, these all have anticholinergic effects besides the basic effects on seratonin and norepinephrine, and these chemical alterations can contribute to more cognitive dysfnctn in those who start to lose levels of acetylcholine. Otherwise not a problem.

Not antidepressants: There is no reason to think that antidepressants would do this. However major depressive disorder does seem to be linked to an increased of alzheimer's disease. On the other hand benzodiazepines like lorazep and valium do seem to increase the risk of dementia. Consider working with your doctor to stop the "tranquilizer a" if possible. Don't hange your medicines without consulting your own doctor.
