Frontal lobe dementia: what to know

The frontal lobes help regulate impulse control, social behaviour, planning, motivation, and flexible thinking. Changes may include socially inappropriate comments, reduced empathy, repetitive routines, loss of initiative, impulsive spending, or difficulty organising familiar tasks. Some people develop word-finding or speech changes. Memory problems can occur, but early behaviour or language changes may be more noticeable. Similar symptoms can arise from depression, medication effects, sleep problems, substance use, or other neurological conditions, so a symptom alone does not establish the diagnosis.

Arrange a GP consultation when changes persist, affect safety, or concern family members. Bring a timeline with examples, current medicines, sleep changes, and any change in work, driving, eating, or finances. Assessment may include physical and cognitive checks, conversations with someone who knows the person well, and further tests when needed. Use calm routines, simple choices, supervision around hazards, and written prompts. Protect dignity while discussing practical plans for care and decision-making.

Get urgent help for sudden confusion, new weakness, facial drooping, loss of speech, a seizure, severe headache, collapse, or a rapid change in behaviour. Seek prompt advice if there is wandering, unsafe driving, aggression that cannot be managed, inability to eat or drink, falls, or new urinary incontinence. A gradual change still deserves review because treatable contributors can coexist with dementia.

Which symptoms should we track? Could medicines, mood, sleep, or another condition be contributing? What assessment is appropriate, and what support is available for the person and their carer?
