Does dementia cause urinary incontinence?

Dementia can affect awareness of bladder signals, the ability to find or reach a toilet, or the steps needed to use clothing and bathroom fixtures. A person may also forget where the toilet is or need more time to respond to urgency.

Leakage may instead relate to a urinary infection, constipation, an overactive bladder, prostate symptoms, reduced mobility, diabetes or a medicine effect. New or suddenly worse incontinence should therefore be reviewed, especially when there is pain, fever, blood in the urine or a change in alertness.

Book a clinical assessment for new, persistent or worsening leakage. Record when accidents occur, the type of leakage, drinks, bowel symptoms and any pain or fever. Bring the medicine list and note changes in memory, walking or ability to reach the bathroom.

Make the route to the toilet clear and well lit, choose easy-to-remove clothing, offer regular toilet visits and keep fluids steady unless a clinician has advised a restriction. Protect dignity with discreet pads and gentle skin care; do not shame or scold the person.

Get urgent medical help for inability to pass urine, severe lower-abdominal pain, blood in the urine, fever with back or side pain, severe weakness, sudden confusion or a person who is difficult to wake. These symptoms can signal a problem requiring prompt treatment.

Ask whether an infection, constipation, medicine or mobility problem could be contributing, whether urine testing is needed, and which bladder strategies are suitable. Ask how to protect the skin and when a continence or dementia service could help.
