Emergency conditions in Parkinson's disease

Parkinson's disease (PD) is a chronic, neurodegenerative disorder that in certain stages can present a series of acute symptoms and signs, the development of which lasts several hours or days. Emergencies in PD can be a direct consequence of the pathophysiology of the disease or a secondary consequence of the administration of antiparkinsonian drugs. Urgent conditions in PD can also occur due to falls, infectious diseases, after deep brain stimulation or surgical treatment of other accompanying diseases. This article describes the following emergency conditions: parkinsonism-hyperpyrexia syndrome, dyskinesia-hyperpyrexia syndrome, occurrence of acute psychosis and delirium during PD. Morbidity and mortality in these disorders are a consequence of the inability to make a timely diagnosis and provide appropriate therapeutic treatment. Timely diagnosis and treatment are very important for reducing the mortality and morbidity rates.
