Signs and Symptoms
Brain Injuries often create impairment or disability which can vary greatly in severity. In cases of serious brain injuries, the likelihood of areas with permanent disability is great, including neurocognitive deficits, delusions (often specifically monothematic delusions), speech or movement problems, and mental handicap. There will also be personality changes. The most severe cases result in coma or even persistent vegetative state. Even a mild incident can have long term effects or cause symptoms to appear years later.
Mental fatigue is a common debilitating experience and may not be linked by the patient to the original (minor) incident. Narcolepsy and sleep disorders are common misdiagnoses.
Brain injury whether from stroke, alcohol abuse, traumatic brain injury, or vitamin B deficiency can sometimes result in Korsakoff's Psychosis, where the individual engages in confabulations. Confabulations involve the inability to separate daydream memory from real memory and the filling in of memory lapses with daydreams. Like all other symptoms of brain injuries, Korsakoff's Psychosis is often mis-diagnosed, in this case as schizophrenia.

Famous quotes containing the words signs and/or symptoms:
“Among all the modernized aspects of the most luxurious of industries, the model, a vestige of voluptuous barbarianism, is like some plunder-laden prey. She is the object of unbridled regard, a living bait, the passive realization of an ideal.... No other female occupation contains such potent impulses to moral disintegration as this one, applying as it does the outward signs of riches to a poor and beautiful girl.”
—Colette [Sidonie Gabrielle Colette] (1873–1954)
“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
