The typical symptoms, problems, difficulties, or dysfunction a person may experience from traumatic brain injury may include the following:
Physical symptoms
Headaches, head pressure, nausea, vomiting, sleep changes, fatigue, weakness in the face or limbs, hearing problems, tinnitus, visual field loss, blurred vision, double vision, eye movement and tracking problems, changes in taste or smell, bad taste in mouth, spasticity, aphasia, dysphagia, dysarthria, dizziness, balance or coordination problems, seizures, and sensitivity to light and/or noise.
Communication problems
Difficulty finding words, reading, understanding written and verbal communication, and writing.
Cognitive or mental issues
Deficits in attention, concentration, memory (short or long-term), speed of processing, new learning, planning, reasoning, judgment, self-awareness, problem solving, abstract thinking, visual spatial, mental or brain fog or fatigue, feeling dazed or hazy, confused, or disoriented.
Behavioral or emotional changes
Depression or anxiety, agitation, irritability, impulsivity, aggression, easily losing temper, or lack of motivation or energy.
Clinical signs of a TBI
- Loss of consciousness immediately following the injury, which may appear as no protective action taken on falling after impact or lying motionless and unresponsive.
- Alteration of mental status immediately following the injury — reduced responsiveness, slowness to respond, agitated behavior, inability to follow two-part commands, or disorientation.
- Complete or partial amnesia for events immediately following the injury, or retrograde amnesia (gap in memory for events immediately preceding the injury).
- Significant drowsiness or inability to wake up, slurred speech, numbness, weakness or difficulty with motor coordination, pupil size asymmetry, repeated vomiting, shaking/twitching or seizures, severe headache that keeps getting worse, or fluid draining from the nose or ears.
Even if it appears to be a minor fall or bump on the head, or if you aren't sure if you injured your brain, go get checked out by a doctor. Waiting could have detrimental effects on your recovery and legal claim.
