Affected individuals often become depressed, uncaring (apathetic), inactive, and unable to act or make decisions (abulic). They become withdrawn, and exhibit poor judgement, reduced planning and organizational skills, and less spontaneous communication. In addition, affected individuals may have difficulty with speech (dysarthria), swallowing (dysphagia), and urinary bladder control (incontinence). Some patients exhibit abnormalities that are similar to those seen in Parkinson disease, such as slowness, poor balance and short, shuffling steps (Parkinsonism). Tremor is usually not a feature.
Many individuals with Binswanger disease have a history of strokes or transient ischemic attacks. Consequently, the symptoms and signs of this disease develop in a stuttering or stepwise fashion; in contrast to the insidious, gradually progressive course of neurodegenerative diseases.
