Prompt, proper diagnosis and treatment can help alleviate some of the problems after a head injury. However, it is usually difficult to predict the outcome of a brain injury in the first few hours or days; a patient's prognosis may not be known fo...

Aphasia is condition characterized by either partial or total loss of the ability to communicate verbally or using written words. A person with aphasia may have difficulty speaking, reading, writing, recognizing the names of objects, or understanding what other people have said.
|
|
|
Aphasia is a communication disorder that occurs after language has been developed, usually in adulthood. Not simply a speech disorder, aphasia can affect the ability to comprehend the speech of others, as well as the ability to read and write.
|
|
Treating AphasiaAphasia occurs when a part of the brain that processes language is damaged. Most people who have a stroke or a brain injury are tested for aphasia.
|
|
|
What Is Aphasia?Aphasia is a loss of language skills.
|
|
|
Aphasia is an impairment of spoken language understanding and expression associated with brain damage. Neurologic etiologies that affect the left cerebral cortex can lead to aphasia (sometimes termed dysphasia).
|
|
A condition, caused by neurological damage or disease, in which a person ' s previous capacity to understand or express language is impaired. In aphasia, the ability to understand language and to translate thoughts into words has been impaired by injury to the brain.

Understanding Traumatic Brain InjuryBreathing, blood flow, and movement are all controlled by the brain. The brain also allows you to think, handle emotions, and make judgments.

Coma, from the Greek word " koma, " meaning deep sleep, is a state of extreme unresponsiveness, in which an individual exhibits no voluntary movement or behavior. Furthermore, in a deep coma, even painful stimuli (actions which, when performed on a healthy individual, result in reactions) are unable to affect any response, and normal reflexes may be lost.

Hearing loss is the total or partial inability to hear sound in one or both ears. See also: Hearing loss of aging
|
|
|
Most people over age 65 have some hearing loss, and by age 80, almost everyone does. Because hearing loss usually occurs slowly over the years, you may not realize your hearing ability has gotten worse.
|
|
|
As you age, some hearing loss is normal. You lose more than the ability to hear how loud a sound is. You also lose the ability to hear certain types of sounds. For example, you might not be able to hear some of the high-pitched sounds of a child's voice.
|
|
|
Hearing loss is any degree of impairment of the ability to apprehend sound. Sound can be measured accurately.
|
|
Hearing begins in the womb- pregnant women have reported feeling the fetus move in response to loud noises at 31 weeks (7 weeks before full-term delivery). Newborns are sensitive to the location, frequency, pitch, and volume of sounds.
|
|
Hearing impairment is the temporary or permanent loss of some or all hearing in one or both ears. There are three types of hearing impairment that occur in young children: conductive hearing loss, a usually temporary interference with the reception of sound from the outer ear to the middle or inner ear sensorineural hearing impairment, a permanent abnormality of the cochlear hair cells of the inner ear, the auditory nerve, or the auditory center of the brain mixed hearing impairment, a combination of conductive and sensorineural impairments Hearing impairments also are classified as prelingual (occurring before a child learns to speak) and post-lingual (occurring after the child has acquired language).

Numbness and tingling are abnormal sensations that can occur anywhere in your body, but are often felt in your hands, feet, arms, or legs.
|
|
Numbness and tingling are decreased or abnormal sensations caused by altered sensory nerve function. The feeling of having a foot " fall asleep " is a familiar one.

Mood disorders are mental disorders characterized by periods of depression, sometimes alternating with periods of elevated mood. While many people go through sad or elated moods from time to time, people with mood disorders suffer from severe or prolonged mood states that disrupt their daily functioning.
|
|
|
Research on the connection between a person ' s mood and the food he or she eats has reveled what many people have long believed, that eating a certain food can influence a person ' s mood- at least temporarily. Research by Judith Wurtman, a professor at the Massachusetts Institute of Technology (MIT), has focused on how certain foods alter one ' s mood by influencing the level of certain brain chemicals called neurotransmitters .

Understanding Affective (Mood) DisordersMost people have mood changes now and then. One day they may feel cranky and the next day, they feel great.

Paralysis is defined as complete loss of strength in an affected limb or muscle group. The chain of nerve cells that runs from the brain through the spinal cord out to the muscle is called the motor pathway.

A seizure is a sudden change in behavior due to an excessive electrical activity in the brain.
|
|
A seizure is a sudden change in behavior characterized by changes in sensory perception (sense of feeling) or motor activity (movement) due to an abnormal firing of nerve cells in the brain. Epilepsy is a condition characterized by recurrent seizures that may include repetitive muscle jerking called convulsions.

Epilepsy is a condition characterized by recurrent seizures that may include repetitive muscle jerking called convulsions.
|
|
A temporary series of uncontrollable muscle spasms brought on by unusual electrical activity in the brain. Also known as convulsion, clonic seizure, or tonic-clonic seizure.
|
|
Children with epilepsy may have seizures only once in a while, or every day. Though seizures can be scary for parents and caregivers, they aren’t painful and are usually brief.
|
|
|
First Aid: SeizuresA seizure results from a sudden rush of abnormal electrical signals in the brain. Symptoms may range from a minor daze to uncontrollable muscle spasms(convulsion).In some cases, the victim may even lose consciousness.

Dysarthria is a speech diagnostic term that can be used to classify various types of neuromuscular speech disturbances. Dysarthria results from notable degrees of one or more abnormalities involving speech musculature, including weakness, paralysis, incoordination, sensory deprivation, exaggerated reflex patterns, uncontrollable movement activities, and excess or reduced tone.
|
|
|
What Is Dysarthria?Dysarthriais a speech problem caused by a lack of control over muscles in the face and mouth.
|
|
Treating DysarthriaDysarthria occurs when the part of the brain that controls speech production is damaged. When this happens, the muscles needed to make certain sounds can’t be used fully.
|
|
Dysarthria is a group of speech impairments due to weakness, incoordination, spasticity, rigidity, or irregular movements caused by damage to the nervous system. Speech abilities depend on the coordinated function of muscles of respiration, phonation (larynx), and articulation.

Breathing that slows down or stops from any cause is called apnea. Apnea can come once in a while and be temporary. This tends to occur with obstructive sleep apnea . Prolonged apnea is means a person has stopped breathing. This is also called respiratory arrest.
