I sometimes struggle to remember names - should I see my doctor?

Dr Mark Porter on memory loss

We all have memory lapses from time to time, and they do become more frequent with age as the brain’s "computing power" starts to wane and it struggles to find the right "file" at the right time. The tricky bit – for both patient and doctor – is working out when these lapses are a sign of more worrying problems.

Worsening memory loss, often for recent events, can be a symptom of the early stages of dementia, particularly Alzheimer’s disease. However, it is often also typically accompanied by a gradual decline in cognitive ability, impacting on everything from navigation skills when driving to being able to carry out complex tasks such as using a computer or following a difficult recipe. Mood and behaviour can be affected too.

I can’t give you a definitive answer, but forgetting names occasionally in your late seventies wouldn’t concern me if it’s your only issue.

However, the fact that it is worrying you enough to write to me suggests it may not be as occasional as you imply, so it’s best not to ignore your symptoms. And here’s why.

Why an early visit to a GP can make a difference

If you book an appointment to see your GP, they might, after delving a bit deeper and putting you through some basic memory and cognitive function tests (a quick questionnaire), be able to reassure you all is fine. Even if they do turn up more worrying cognitive impairment, the sooner this is identified, the better.

First, it may have nothing to do with dementia but could be related to a far more treatable underlying cause such an underactive thyroid, vitamin B12 deficiency, depression or even a side effect of medication.

Many older people take lots of different medicines, some of which can have significant effects on the brain. Common culprits include sleeping tablets (prescription only and over-the-counter types), old-fashioned antihistamines (eg Piriton), diazepam (Valium), antidepressant/nerve pain treatment amitriptyline, and opioid painkillers like codeine.

Second, if he or she can’t identify an obvious underlying reversible cause, your GP can refer you on to a specialist clinic to investigate further, where they might start treatments that may help symptoms and, sometimes, even slow progression (but be aware even the very latest dementia treatments won’t help everyone).

However, early diagnosis isn’t just about the medical benefits. Confirmation can also help you access any benefits and social care you are entitled to and give you and your family time to plan for the future: everything from booking a dream trip to seeking professional advice about legal and financial matters.

Bottom line? Please discuss your concerns with your doctor.
