Poor hygiene can be a sign of self-neglect, which is the inability or unwillingness to attend to one's personal needs. Poor hygiene often accompanies certain mental or emotional disorders, including severe depression and psychotic disorders. Dementia is another common cause of poor hygiene. Other people may develop poor hygiene habits due to social factors such as poverty or inadequacy of social support. Physical disabilities can also interfere with one's ability to care for oneself and may result in an individual being unable to attend to personal hygiene. There is no treatment for poor hygiene, although antipsychotic and antidepressant medications are used when certain mental illnesses are the cause of this behavior.
Other causes of poor hygiene
- Brain Trauma
- Delusional Disorder
- Drug-Induced Psychosis
- Lack of Social Support
