The wider you read the wider you may find the gap between what health professionals profess in professional journals etc aND what comes out of their mouths to patients.
Parkinson’s disease: an overview The Pharmaceutical Journal 26 FEB 2000 David Burn
Perhaps the most important diagnosis to consider when a patient presents with parkinsonism is whether their symptoms and signs may be drug-induced. This is because drug-induced parkinsonism (DIP) is potentially reversible upon cessation of the offending agent.
Prescribed drugs and neurological complications K.A.Grosset, D.G.Grosset J Neurol Neurosurg Psychiatry 2004;75:iii2-iii8
Drug induced movement disorders are common. In epidemiological studies between a third and a half of parkinsonism is caused by medication. Considering antidepressant treatment for patients with Parkinson’s disease is complex. … some patients report worsened parkinsonism. A Cochrane systemic review concluded that there are insufficient data on the effectiveness and safety of antidepressant therapies in Parkinson’s disease.

Can Sertraline Induce Parkinson’s Disease? R.J.Gregory & J.F.White Psychosomatics March–April, 2001Vol.42, Issue 2, P.163–164
Extrapyramidal side effects of sertraline and other selective serotonin reuptake inhibitors (SSRIs) have been noted extensively in the literature. We report on a patient who developed irreversible Parkinson’s disease shortly after initiation of treatment with sertraline.

A Case of SSRI Induced Irreversible Parkinsonism S.Dixit, S.A.Khan, and S.Azad J Clin Diagn Res. 2015 Feb; 9(2):
Serotonin specific reuptake inhibitors (SSRI)… are sometimes associated with extrapyramidal side effects including Parkinsonism. We report a case of generalized anxiety disorder on treatment with SSRI (fluoxetine / sertraline) who developed irreversible Parkinsonism.

We have not, however, observed a total regression of symptoms and signs in all our patients during follow-up. This may be due to insufficient duration of follow-up or could point to certain irreversible processes that may begin and go clinically unnoticed at any time during VPA treatment. It could be argued that factors other than VPA may contribute to the initiation and maintenance of neuronal damage.

These are the steps pharmaceutical companies routinely work through, based on which they often decide their drug has caused a problem, while still denying in public that it does so. [developed from the Naranjo algorithm (1981) for estimating the probability of adverse drug reactions]
