Physical consequences which may occur after a brain injury are weakness, decreased muscular control, paralysis, seizures, sensory loss and a difficulty in speaking and swallowing. If a patient has loss of motor control or weakness on one side of the body this is referred to as hemiparesis. If this is the case poor balance, inability to plan movements of limbs, decreased endurance and poor coordination will be obvious signs. Seizures can occur immediately or be delayed, possibly months or years from the accident. It is possible a patient will not be aware they have had a seizure and just be confused, so if this is not witnessed it is hard to use to prove TBI.
Other noticeable effects are an impact to sight, sound, touch, taste and smell. A TBI victim can also lose sensation to various parts of the body or become hypersensitive. They can have vision loss on one side of the body or struggle to know the spatial relationship of their arms and legs.
Fatigue is another common sign and can sometimes be very profound, with an inability to stay alert. It can be confused for a person being unmotivated. Speech disorders can also develop after these injuries as well as difficulties with chewing and swallowing.
Changes in sleep can also be observed in TBI patients. If there are disruptions to memory, attention, perception and concentration this should be pointed out to a jury as these are indications of TBI.
