Descrição

Perry syndrome is a progressive brain disease that is characterised by four major features: a pattern of movement abnormalities known as parkinsonism, psychiatric changes, weight loss, and abnormally slow breathing (hypoventilation). These signs and symptoms typically appear in a person's forties or fifties.

Parkinsonism and psychiatric changes are usually the earliest features of Perry syndrome. Signs of parkinsonism include unusually slow movements (bradykinesia), stiffness, and tremors. These movement abnormalities are often accompanied by changes in personality and behaviour. The most frequent psychiatric changes that occur in people with Perry syndrome include depression, a general loss of interest and enthusiasm (apathy), withdrawal from friends and family, and suicidal thoughts. Many affected individuals also experience significant, unexplained weight loss early in the disease.

Hypoventilation is a later feature of Perry syndrome. Abnormally slow breathing most often occurs at night, causing affected individuals to wake up frequently. As the disease worsens, hypoventilation can result in a life-threatening lack of oxygen and respiratory failure.

People with Perry syndrome typically survive for about 5 years after signs and symptoms first appear. Most affected individuals ultimately die of respiratory failure or pneumonia. Suicide is another cause of death in this condition.
