Drug-induced parkinsonism (DIP) has been claimed to be the most prevalent cause of secondary parkinsonism in clinical practice in the Western world. Since the first descriptions in the early 1950s the prevalence of DIP seems to be increasing and approaching that of idiopathic Parkinson's disease (iPD) due to the aging of the population and the rising of polypharmacotherapy. Despite the wide interest this subject has raised in the past, it seems to be frequently overlooked by the medical community. ⋯ Levodopa and dopamine receptor agonists might be an option in selected cases in which dopamine nerve terminal defects are present. The weight and scope of DIP varies with the age and underlying health of the patient, imposing a significant burden on the elderly who, in many cases, experience significant functional deterioration that leads to hospitalization and has vast economic consequences. This article reviews the epidemiology, pathogenic mechanisms, implicated drugs, clinical features and management of DIP and highlights the need for increased awareness of this iatrogenic condition.

Older people in general and care home residents in particular are at high risk of suboptimal or inappropriate prescribing. To date, research into potentially inappropriate prescribing (PIP) has not focused on care home residents and/or has not utilized the recently developed and validated Screening Tool of Older Persons' potentially inappropriate Prescriptions (STOPP) criteria. ⋯ This study found that over two-fifths of older people with dementia residing in six residential care homes in England were prescribed at least one PIM at each timepoint. Long-term (i.e. >1 month) antipsychotics, NSAID use for >3 months and PPI use at maximum therapeutic dosage for >8 weeks were the most prevalent PIMs. Regular medication review that targets, but is not limited to, these medications is required to reduce PIP in the residential care home setting. The STOPP criteria represent a useful tool to facilitate such review in this patient population.
