Drug-induced Parkinsonism

Drug-induced or secondary Parkinsonism is a neurological disorder caused by the long-term use of certain medications or toxins. It is caused by the overstimulation of specific brain areas due to the presence of drugs or toxins in the body. The most common drugs that have been linked to Drug-induced Parkinsonism are neuroleptics (medications that act on the central nervous system to produce sedation, decrease anxiety, and decrease agitation in certain mental disorders), anticonvulsants (medications used to prevent or reduce the frequency of seizure attacks), and dopamine agonists (drugs that mimic the action of dopamine in the brain and help to control movement). It is important to note that certain lifestyle factors, such as smoking, can also put people at increased risk for Drug-induced Parkinsonism. In general, people who are taking multiple medications simultaneously and those taking medications for long periods of time are most at risk for developing Drug-induced Parkinsonism. The symptoms of Drug-induced Parkinsonism are similar to those of Parkinson's disease, such as tremor, rigidity, slow movements, impaired balance and coordination, and issues with posture and gait. It is also important to note that people with Drug-induced Parkinsonism typically do not experience the cognitive decline associated with Parkinson's disease, although some people may experience mild cognitive deficits associated with long-term use of certain medications. In most cases, the symptoms of drug-induced Parkinsonism can be resolved by discontinuing the medication (or toxins) that are causing them. However, there are some cases where the patient must remain on the drug due to underlying medical conditions, and in those cases it is important to work with the patient’s healthcare team to find an alternative medication that does not cause Drug-induced Parkinsonism or other serious side effects. In conclusion, Drug-induced Parkinsonism is a potentially serious neurological condition that can be caused by certain medications or toxins. The symptoms closely resemble those of Parkinson's disease and typically improve upon discontinuation of the offending drug (or toxin). Therefore, it is important for patients to be aware of the potential risks associated with the medications they are taking and to consult with their healthcare team about alternative treatment options if drugs (or toxins) trigger symptoms of Drug-induced Parkinsonism.
