Erectile disorders can indeed occur in people with Parkinson's disease. Sometimes there is damage to the autonomic nervous system by parkinsonism. In some forms of atypical parkinsonism (such as multiple system atrophy (MSA), this is more common. But usually, there are many other causes of erectile dysfunction, such as high blood pressure, diabetes, depression or drug use (antidepressants). Also lifestyle factors such as smoking, being overweight and alcohol use may also have an effect. There are also psychological factors such as fear of failure and performance pressure. Here a interdisciplinary approach involving the general practitioner, neurologist and urologist can help to identify the underlying cause and initiate causative or symptomatic treatment.
