Can memory and attention improve after a brain injury?
Yes, though not usually by restoring the damaged function itself. The approaches with the strongest evidence teach strategies and train attention in the tasks that matter, so the person manages daily life better even where the underlying memory has changed permanently. That distinction shapes the whole programme.
What does cognitive rehabilitation actually do?
The international guidelines for cognitive rehabilitation after traumatic brain injury recommend teaching internal strategies and external aids for memory, and training attention within functional tasks. They recommend against relying on computerised drills on their own, because improvement on the exercise rarely transfers to daily life.
That is the single most useful thing a family can know before buying a brain-training subscription. Getting faster at a game is not the same as remembering to take medication.
Which problems respond best?
Prospective memory — remembering to do something later — responds well, because it can be scaffolded with calendars, alarms and routines that eventually become habit. Attention in a single structured task improves with practice. Planning and organisation improve with explicit step-by-step methods that are rehearsed in real activities.
What responds least is speed of processing in complex, noisy environments, which is why advice about workload and environment often does more than any exercise.
Why is fatigue treated as a cognitive problem?
Because it is one. After brain injury, attention and memory deteriorate sharply with tiredness, and a person assessed at nine in the morning can look like a different patient at four in the afternoon. Programmes that ignore this produce sessions that measure fatigue rather than ability.
Pacing, planned rest and scheduling demanding tasks for the best hours are therefore part of the treatment, not lifestyle advice bolted on at the end.
How do you know it is working?
By measuring the target activity, not the test score. If the goal is managing medication independently, the measure is doses taken correctly over a week. If the goal is returning to study, the measure is time on task and work completed.
Neuropsychological testing is used to understand the profile and to guide the plan. It is a poor outcome measure on its own, because a person can improve on a subtest while daily life is unchanged.
Frequently asked questions
Do brain-training apps help?
They reliably improve performance on the app. Guidelines do not support computerised training used alone, because the gains transfer poorly. Used as one part of a therapist-led programme with functional goals, they have a place.
Is it too late two years after the injury?
No. Strategy training and environmental change work at any stage, because they do not depend on spontaneous neurological recovery. What the assessment settles is which of the two the programme should lead with.
Should the family be in the sessions?
For memory and organisation work, usually yes. The strategies have to be used at home by the people who are there, and a strategy taught only to the patient tends to disappear within weeks.

Cognitive Cognitive What is visual neglect after a stroke?
Neglect is a problem with attention, not eyesight, in which a person does not notice or respond to one side of space or their own body, usually the left side after a right-sided stroke. They may eat food from only one side of the plate or bump into doorways. Scanning training and practical strategies help, and safety measures are important.Read moreCognitive When can you drive again after a stroke or brain injury?
Driving after a stroke or brain injury depends on recovery of vision, attention, reaction time, judgement and limb control, and on national licensing rules. In the UK, DVLA guidance lets car drivers resume one month after a stroke if recovery is satisfactory; after brain injury, relicensing usually takes 6 to 12 months. A medical assessment decides.Read more
