Several neurological diseases cause constipation or faecal incontinence restricting social activities and influencing quality of life. As several new treatment modalities have become available within the last few years, doctors treating patients with neurological diseases should be aware of the symptoms and have a basic knowledge of relevant treatment options. Constipation and faecal incontinence are common symptoms in patients with traumatic spinal cord injuries, spina bifida, multiple sclerosis, diabetic polyneuropathy, Parkinson's disease, stroke, and cerebral palsy. New treatment modalities are: prokinetic agents, enemas administered through the enema continence catheter or through an appendicostomy, and biofeed-back. Sacral nerve stimulation is still mostly at an experimental level and colostomy should be restricted to the few patients with most severe problems resistant to other therapy.
