Some late sequelae of head injuries due to road accidents.

THE effects of most forms of injury are apparent soon after it has taken place, and, because of the briefness or absence of clouding of consciousness, the patient is immediately aware of them. The late effects of head injury, on the other hand, may not be apparent for months or years, and they may be even more unpleasant and disabling than the initial symptoms. They have far-reaching social effects, and may be responsible for a complete change in the patient's way of life. The patient may even have difficulty in attributing them to the accident.
