Dementia in the elderly is a degenerative neurological disease, and there are currently no particularly effective treatments. In the later stages, it is very common for the elderly to experience urinary incontinence. This is mainly because in the later stages, the autonomic nervous system is affected. Damage to the autonomic nerves leads to dysfunction of the sphincter muscles, resulting in urinary incontinence. Currently, there are no particularly good treatments for urinary incontinence caused by dementia, but some common methods are as follows. First, it is important to kindly remind and encourage the elderly to go to the bathroom frequently, asking every one to two hours whether they feel the need to urinate, which can help avoid urinary incontinence. Second, bathrooms must have conspicuous signs that are prominently placed to help the elderly locate the restrooms easily. Third, when necessary, the elderly can be given diapers to wear to avoid embarrassment from wetting their pants. Also, it's crucial to provide psychological comfort to the elderly and avoid causing them excessive psychological burden. Additionally, other causes must be ruled out. If there is a urinary tract infection or some other urinary system disease causing the incontinence, treatment of the primary disease should be undertaken.
