One does not have to demonstrate impaired function in all areas commonly effected by traumatic brain injury. Any brain function can be disrupted by brain trauma. That means the likelihood of experiencing impairments in cognition, as well as physical manifestations, could be in one area or a group of areas. Therefore we need to know about them.
- excessive sleepiness,
- difficulty concentrating,
- impaired memory,
- faulty judgment,
- emotional outbursts,
- disturbed sleep,
- diminished libido,
- difficulty switching between two tasks, and
- slowed thinking.
Over the next few weeks we will explore these symptoms in greater depth. Lets take a look at excessive sleepiness and its counterpart, insomnia.
Many of my TBI clients have problems. Along with lack of initiative and other symptoms (but not necessarily all) comes excessive sleepiness (always being tired) and insomnia (inability to sleep).
Sleepiness is common following traumatic injury, particularly TBI, with more severe injuries resulting in greater sleepiness. Sleepiness improves in many patients, particularly those with TBI. study
But this study should be evaluated with this in mind: Is "sleepiness" something attached to the traumatic brain injury as an on again and off again ordeal? And how is the inability to sleep, "insomnia," factored in? These are gray areas.
Comparing posttraumatic sleepiness rates between studies is difficult for many reasons. The definition of sleepiness, which may be subjective or objective, is often inconsistent among studies. The time from injury until sleepiness assessment can vary, and measures of TBI severity are often unique. Also, different studies contain patients with variable TBI severity. study
Another consideration is when the sleepiness became a problem. Was it after the date of injury? Was it not there before the injury? If yes then no: we have a match.
