Psychotic Disorders

Objective To provide family physicians with an approach to the management of
motor and nonmotor symptoms of Parkinson disease (PD).
Sources of information Published guidelines on the management of PD were
reviewed. Database searches were conducted to retrieve relevant research
articles published between 2011 and 2021. Evidence levels ranged from I to III.
Main message Family physicians can play an important role in identifying and
treating motor and nonmotor symptoms of PD. Family physicians should initiate
levodopa treatment for motor symptoms if they affect function and if specialist
wait times are long, and they should be aware of basic titration approaches
and possible side effects of dopaminergic therapies. Abrupt withdrawal of
dopaminergic agents should be avoided. Nonmotor symptoms are common and
underrecognized and are a major factor in disability, quality of life, and risk of
hospitalization and poor outcomes for patients. Family physicians can manage
common autonomic symptoms such as orthostatic hypotension and constipation.
Family physicians can treat common neuropsychiatric symptoms such as
depression and sleep disorders, and they can help recognize and treat psychosis
and PD dementia. Referrals to physiotherapy, occupational therapy, speech
language therapy, and exercise groups are recommended to help preserve function.
Conclusion Patients with PD present with complex combinations of motor
and nonmotor symptoms. Family physicians should have basic knowledge of
dopaminergic treatments and their side effects. Family physicians can play
important roles in management of motor symptoms and particularly nonmotor
symptoms and can have a positive impact on patients’ quality of life. An
interdisciplinary approach involving specialty clinics and allied health experts
is an important part of management.
