There are several ways in which medical and psychological professionals diagnose brain injuries. The method will depend on the nature and extent of the injury. Some examples of diagnostic tools are MRIs, CT scans, PET scans and EEGs. In addition, professionals may study a person's behaviors, movements and personality.

the brain is involved in just about everything we do, injury to the brain can have a very wide range of effects. These effects vary from one person to another depending on the exact nature of the brain injury and its severity. It is helpful to distinguish between the initial effects when the person first sustained their brain injury and the longer-term effects. Read more about the effects of brain injury.

Traumatic Brain Injury (TBI) is defined as sudden, permanent damage to the brain caused by external, mechanical forces (e.g., a blow to the head suffered during a motor vehicle accident). Thus, there is a clear distinction between TBI and brain injury caused by internal events (e.g., stroke, anoxia, tumor), developmental disabilities (e.g., mental retardation, cerebral palsy, autism), and progressive illnesses such as Alzheimer's Disease and Parkinson's Disease.

The functions achieved by the brain of the human newborn are almost entirely in the brainstem. They have to do mostly with basic life processes such as breathing, consciousness, simple movement of the body, the circulation of the blood, heat regulation, the ability to suck, swallow and digest food and the collection and discharge of body wastes. It is when disease or injury affects the brainstem, especially pons and medulla, that life is seriously threatened.

The treatment of brain injury occurs in a number of different stages and differs greatly from case to case due to differences in the severity and nature of the injury. When an injury is a result of an accident the initial treatment may occur before the person reaches hospital. The paramedics at the scene of the accident and en route to the hospital will work to stabilise the person's condition and give immediate assistance.

A severe brain injury occurs when trauma to the brain produces a significant neurological injury, resulting in physiologic changes to a person's brain. Four types of injury may cause trauma to the brain: bull; Closed head injuries occur when the brain tissue is injured by hitting the inside of the skull. This can cause bleeding, bruising, tissue damage and increased intra-cranial pressure or fluid buildup

Mild traumatic brain Injury is also called subtle acquired brain injury. People with mild or subtle brain injuries have cognitive, psychological and physical symptoms that occur after the injury. They usually do not experience a prolonged period of unconsciousness or coma. In fact, some individuals report no loss of consciousness.

It is the impairment of normal brain function due to a neurological insult, such as: open or closed head injury (traumatic brain injury or TBI), select cerebral vascular lesions (i.e., aneurysm, hemorrhage, brain stem stroke), hypoxic event (loss of oxygen .. i.e., near drowning), intracranial tumor, and select neurological diseases (i.e., encephalopathy). Well, that is a technical definition. Not very satisfying, is it? It's very impersonal and doesn't really even begin to answer the question.

Many people wonder as to how a person with a scientific and logical temperament, can lend any credence to the belief of life after death. People assume that anyone believing in the hereafter is doing so on the basis of blind belief. My belief in the hereafter is based on a logical argument. There are more than a thousand verses in the Glorious Qur'an, containing scientific facts (refer my book "Qur'an and Modern Science-Compatible or Incompatible?").

Any head injury can cause disruption of brain functions and can result in physical, cognitive, and psychosocial/emotional/interpersonaI impairment.

Approximately one half (48%) of all Traumatic Brain Injury (TBI) cases are caused by motor vehicle accidents. Other major causes of TBI include falls (21%), non-firearm assaults (12%), sports/recreational activities (10%), and firearms (6%). However, in urban areas, which tend to have higher rates of crime, assaults make up a greater percentage of TBI cases, in some surveys as much as 40%.

According to the Center for Disease Control in Atlanta, Georgia, the average TBI incidence rate (including both hospitalization and mortality rate) is 95 per 100,000 people. Each year over 80,000 Americans survive a hospitalization for traumatic brain injury, but are released with TBI-related disabilities. Approximately 5.3 million Americans today live with a TBI-related disability.

Many types of impairments may occur because of TBI. These injuries may impair cognition, including concentration, memory, judgment, and mood. They may also affect movement abilities, including strength, coordination, and balance. Finally they can impair sensation, including tactile sensation and special senses such as vision. TBI sometimes causes seizure disorders (epilepsy). Nearly 1% of individuals with severe TBI survive in a state of persisting unconsciousness.
