When should you see a doctor about memory problems?

Memory slips can accompany stress, depression, poor sleep, medication effects, or illness. Insomnia, obstructive sleep apnoea, hypothyroidism, vitamin B12 deficiency, and Long COVID may affect concentration or recall. Dementia is one possible explanation, but memory problems have several causes and a symptom alone cannot identify which one applies.

Keep a brief record of examples, onset, sleep quality, mood, medicines, alcohol use, recent illness, and any effect on cooking, work, driving, appointments, or finances. Bring a trusted person if possible, since they may describe changes you have not noticed. Use calendars, reminders, and one regular place for keys and medicines while waiting.

Seek urgent help for sudden confusion, new trouble speaking, facial drooping, one-sided weakness, a severe headache, seizure, fainting, or confusion after a head injury. These changes can need immediate assessment rather than a routine appointment.

Ask whether a medicine review, physical examination, blood tests, sleep assessment, or cognitive testing is appropriate, and which changes should prompt follow-up. Ask how to stay safe with driving, work, and medicines if tasks are becoming difficult.
