Wasserepulsivität

Wasserepulsivität is a rarely used German-language term that describes impulsive or compulsive behaviors related to water. It is not part of standardized diagnostic manuals, and the exact definition and scope vary between authors and case reports.

Clinical features commonly described include sudden urges to perform water-related actions such as drinking water, splashing, spraying, or ritualized handling of water. These behaviors may be performed repetitively and can be associated with brief relief of distress followed by distress or impairment when the act cannot be carried out. The clinical presentation is variable, and the severity can range from mild to clinically significant.

Associations and differential diagnosis: Wasserepulsivität has been reported in the context of obsessive–compulsive spectrum disorders, tic disorders, attention-deficit/hyperactivity disorder, autism spectrum disorder, or after neurological injury. Important differential diagnoses include genuine medical causes of polydipsia, stereotypies related to neurodevelopmental conditions, and other impulse-control or compulsive disorders. Comprehensive assessment should exclude medical factors that could explain abnormal water intake or handling.

Diagnosis and treatment: There are no standardized diagnostic criteria for Wasserepulsivität. Evaluation relies on clinical interview, behavioral observation, and assessment of comorbid conditions. Treatment is typically tailored to the individual and may include cognitive-behavioral therapy with exposure and response prevention, habit reversal strategies, and pharmacotherapy addressing comorbid conditions (for example SSRIs for OCD or stimulants for ADHD). Management of any underlying medical issues is important.

Research status: Evidence for Wasserepulsivität remains limited to isolated case reports and theoretical discussions. More systematic research is needed to clarify its nosology, prevalence, and effective treatments.
