How effective is mental health assessment for dementia?

A clinician may ask about memory, language, orientation, mood, sleep, behaviour and changes in everyday tasks. A family member or trusted person can provide useful examples of changes over time. The clinician may also review medicines, physical health, hearing, vision and stress, since these can affect thinking. Assessment helps distinguish urgent changes from a gradual pattern and shows what support, monitoring or specialist evaluation may be appropriate. It is one part of a wider dementia assessment.

Write down examples such as missed appointments, repeated questions, getting lost, difficulty managing money or changes in personality. Bring a medicine list and, if the person agrees, invite someone who knows their usual abilities. Ask what further checks are needed, how to support independence safely and when reassessment is planned. See [Mental Health Assessment](/treatments/consultations-and-assessment/mental-health-assessment/) and [Dementia](/conditions/dementia/).

Seek urgent medical help for sudden confusion, new weakness, trouble speaking, a severe headache, fainting, a head injury, fever or a rapid change in behaviour. Arrange timely review for repeated falls, unsafe driving, wandering, medication errors, hallucinations or inability to eat and drink safely. Sudden confusion is not the same as a slowly progressive memory problem and needs prompt attention.

Ask which changes are most concerning, what reversible contributors should be checked, whether a specialist referral is needed, and how family members can support daily safety.
