Concussion with loss of consciousness seems to have more negative impact on the life quality in the long term than concussion without. A recent large study found that nearly half of people who have had a concussion with loss of consciousness, are living with a disability.
The greatest amount of disability was related to mobility (think about walking the stairs or standing up from an armless chair), followed by general physical activities (such as carrying heavy objects or standing for long periods) and by being limited in the amount or type of work to be done. These 3 areas of disability had 38%, 36% and 35% respectively.
The only area that did not show any relation between concussion and disability was grip strength.
