Traumatic Brain Injury

A brain injury is rarely one injury. There is the damage at the point of impact, damage on the opposite side as the brain moves inside the skull, and diffuse injury to the long fibres that connect regions to each other. The third kind explains why two people with similar scans can have entirely different problems.

This is also why brain injury is harder to describe than stroke. A stroke usually damages one territory and produces a recognisable pattern. A brain injury can leave walking intact and destroy the ability to hold a plan in mind for ten minutes — and the second disability is the one that decides whether someone works again.

After a significant brain injury there is a period during which the person is awake but not laying down continuous memory. They may talk, follow instructions and even walk, and remember none of it afterwards. This is post-traumatic amnesia, and its duration is the single most useful severity measure available.

The relationship is close to linear: the odds of returning to productive activity fall by around 14 per cent for each additional week that post-traumatic amnesia continues 5. Where it resolves within 24 hours, the probability of returning to work or study is strong 5.

International guidance recommends measuring it daily with a validated scale until it resolves, rather than estimating it afterwards. If your relative is still in this phase when you contact us, that measurement is more useful to a rehabilitation physician than any imaging.

During post-traumatic amnesia many people are restless, repetitive, sometimes aggressive with people they love. Families read this as the person having changed permanently. Usually it is the injury passing through a stage, and it settles as memory returns.

It is managed mostly by the environment rather than by medication: a quiet room, the same faces, the same order of the day, and less stimulation rather than more. Sedating someone through this phase is easy and it slows the recovery it is supposed to help.

We tell families what this phase looks like before it starts, because the ones who were warned cope with it very differently from the ones who were not.

Attention, memory and planning are treated in the same programme, on the same days, by a team that talks to each other. Splitting them is common and it produces a person who can walk down a corridor but cannot remember why they set out.

In practice this means the physiotherapy session doubles as attention training, and the occupational therapy session works on sequencing a real task — making a drink, managing medication — rather than on abstract exercises. Skills learned in context transfer better than skills learned at a desk.

Some families arrive having been told their relative is in a vegetative state. That diagnosis is wrong more often than most people realise: in one widely cited study, when the diagnosis was made by clinical impression rather than a standardised assessment, 41 per cent of patients thought to be vegetative were in fact minimally conscious 4.

The reason is that awareness can be masked by everything else the injury has caused: the person cannot speak, cannot move reliably, cannot see well. A standardised, repeated assessment finds responses that a single bedside conversation does not.

So we reassess rather than inherit the label. What we cannot do is promise that reassessment changes the answer — in most cases it confirms it. It is a better diagnosis, not a treatment, and we will not let it be sold as hope.

Meaningful change continues for longer after brain injury than after stroke: follow-up studies of survivors five to ten years after injury still find more improvement than decline 6. This changes what a four to eight week programme is for. It is not the whole recovery; it is an intensive block inside a longer process, designed to be repeated.

It also changes how goals are set. A goal that is out of reach this month may be reasonable next year, and saying so is more useful than either false optimism or premature closure.

Relatives are usually the first to detect that someone is more alert, more able to follow a conversation, or more irritable than yesterday. In brain injury this is not sentiment — it is clinically useful information, and it is collected rather than politely acknowledged.

The companion is also the person who will manage the routine at home: the memory aids, the fatigue limits, the structure of the day. They are trained during the stay rather than briefed at the end of it.

Four to eight weeks as an inpatient, four to six hours of active therapy a day. Physiotherapy for balance, walking and arm function; occupational therapy for daily tasks and the cognitive work embedded in them; speech and language therapy where communication or swallowing is affected; and robotic or virtual-reality sessions where they fit the plan.

Fatigue is planned for rather than pushed through. After brain injury it is a symptom, not a lack of effort, and a schedule that ignores it produces worse outcomes than a lighter schedule that respects it.
