Does dementia cause memory problems?

Dementia can affect recently learned information first, such as appointments, conversations or where an item was placed. A person may repeat questions, lose track of a discussion or need more help with familiar tasks. Changes can also involve language, planning, judgement or recognising places, rather than memory alone.

Memory lapses also occur with poor sleep, stress, depression, medication effects, hearing problems and some medical conditions. A gradual change that interferes with daily activities deserves an assessment; it does not by itself establish the cause.

Arrange a primary-care appointment if memory changes are recurring, worsening or affecting medicines, finances, cooking, driving or personal safety. Take a list of medicines and supplements, describe when the change began, and bring examples from someone who knows the person well.

Until the cause is clearer, use a calendar, written reminders, labelled storage and a regular routine. Avoid changing prescribed medicines without advice. Support good sleep, regular meals, hydration and hearing or vision care.

Seek urgent medical help for sudden confusion, a new severe headache, weakness or numbness on one side, trouble speaking, a seizure, fainting, a head injury or a rapidly changing level of alertness. These signs may indicate a problem needing prompt assessment rather than a gradual memory disorder.

Ask what changes should be assessed, whether medicines or sleep could contribute, which memory and thinking checks are appropriate, and whether hearing, vision or blood tests are needed. Ask how to make the home safer while the evaluation continues.
