Multiple Head Injuries and Dementia

According to statistics, it is thought that repeated head injuries are the third most common cause of dementia. Repeated head injuries can be the result of concussions which are common with boxers in particular but with many other athletes as well.

Most in the medical field now agree that concussions are a mild head injury. Historically, concussions involved loss of consciousness but this does not always happen. However, when it does, it is considered to be a more serious brain injury than if there had been no loss of consciousness.

In the case of boxers, the onset of early dementia can begin about fifteen years following the first concussion. It is estimated that between fifteen and twenty percent of boxers can be affected but also hockey, soccer and football players who suffer multiple concussions can suffer the effects as well.

When concussions initially occur, sadly they may not be identified as such or may even be ignored. However, with rest, in time they will heal. Some of the possible initial symptoms of a concussion are headaches, dizziness, vomiting or nausea, blurred vision, confusion, slurred speech, tearfulness or irritability. There is no indication that someone who has suffered only one concussion is at risk for dementia.

It is important for athletes who are at risk for developing dementia in later life to do things to prevent or delay the onset of it. The following preventative measures should be taken:

- it is important to exercise consistently;
- eat a brain healthy diet;
- avoid smoking;
- avoid alcohol;
- challenge your brain by learning new things;
- get a lot of rest.

The nature of dementia depends on the type and location of the head injury and the person's characteristics previous to their injury. Dementia related symptoms are:

- memory difficulties;
- tremors and lack of coordination;
- speech and communication problems;
- difficulty walking;
- inappropriate behavior and paranoia;
- explosive anger;
- cognitive and emotional difficulties;
- personality changes;
- delusions and or hallucinations, confusion and disorientation;
- a decrease in problem solving abilities and judgment;
- depression and irritability;
- declining mental ability to think and concentrate;
- and possibly other prolonged and irreversible problems such as impaired recognition which will impact daily living and independence.

Rest is important during the healing process . A return to any sports' activities should be based on the severity of the concussion. Injured players should be symptom-free for one week following a concussion but if they become unconscious, all sports activities should be avoided for a month after all symptoms have cleared. It is important to avoid a second concussion until well after all symptoms have cleared. And if there is any swelling or bleeding of the brain, sports and the risk of another concussion, should be avoided for an indefinite period of time.
