Babcock Law Firm provides as benefit to our clients, The Traumatic Brain Injury Glossary of Terms. It includes definitions for over 200 brain injury related terms from HDI's Brain Injury Glossary.
Abstract Concept
A concept or idea not related to any specific instance or object and which potentially can be applied to many different situations or objects. Persons with cognitive deficits often have difficulty understanding abstract concepts.

Abstract Thinking
Being able to apply abstract concepts to new situations and surroundings.

Abulia
Absence or inability to exercise will-power or to make decisions. Also, slow reaction, lack of spontaneity, and brief spoken responses. Usually associated with damage to a cerebellar vessel.
Acalculia
The inability to perform simple problems of arithmetic.
Acute Care
The phase of managing health problems which is conducted in a hospital on patients needing medical attention.
Acute Rehabilitation Program
- Primary emphasis is on the early phase of rehabilitation which usually begins as soon as the patient is medically stable. The program is designed to be comprehensive and based in a medical facility with a typical length of stay of 1-3 months. Treatment is provided by an identifiable team in a designated unit. See Program/Service Types.
Adaptive/Assistive Equipment
- A special device which assists in the performance of self-care, work or play/leisure activities or physical exercise.
ADL
- Activities of daily living. Routine activities carried out for personal hygiene and health (including bathing, dressing, feeding) and for operating a household.
Affect
- The observable emotional condition of an individual at any given time.
Agnosia
- Failure to recognize familiar objects although the sensory mechanism is intact. May occur for any sensory modality.
Agraphia
- Inability to express thoughts in writing.
Alexia
- Inability to read.
Ambulate
- To walk.
Aneurysm
- A balloon-like deformity in the wall of a blood vessel. The wall weakens as the balloon grows larger, and may eventually burst, causing a hemorrhage.
Anomia
- Inability to recall names of objects. Persons with this problem often can speak fluently but have to use other words to describe familiar objects.
Anosmia
- Loss of the sense of smell.
Anoxia
- A lack of oxygen. Cells of the brain need oxygen to stay alive. When blood flow to the brain is reduced or when oxygen in the blood is too low, brain cells are damaged.
Anterograde Amnesia
- Inability to consolidate information about ongoing events. Difficulty with new learning.
Anticonvulsant
- Medication used to decrease the possibility of a seizure (e.g., Dilantin, Phenobarbital, Mysoline, Tegretol).
Antidepressants
- Medication used to treat depression.
Aphasia
- Loss of the ability to express oneself and/or to understand language. Caused by damage to brain cells rather than deficits in speech or hearing organs.
Apraxia
- Inability to carry out a complex or skilled movement; not due to paralysis, sensory changes, or deficiencies in understanding.
Aprosodia
- A condition in which there is a loss of production or comprehension of the meaning of different tones of voice.
Arousal
- Being awake. Primitive state of alertness managed by the reticular activating system (extending from medulla to the thalamus in the core of the brain stem) activating the cortex. Cognition is not possible without some degree of arousal.
Articulation
- Movement of the lips, tongue, teeth and palate into specific patterns for purposes of speech. Also, a movable joint.
Aspiration
- When fluid or food enters the lungs through the wind pipe. Can cause a lung infection or pneumonia.
Astereognosia
- Inability to recognize things by touch.
Ataxia
- A problem of muscle coordination not due to apraxia, weakness, rigidity, spasticity or sensory loss. Caused by lesion of the cerebellum or basal ganglia. Can interfere with a person's ability to walk, talk, eat, and to perform other self care tasks.
Atrophy
- A wasting away or decrease in size of a cell, tissue, organ, or part of the body caused by lack of nourishment, inactivity or loss of nerve supply.
Attendant Care
- Provision of assistance in activities of daily living for a person with disability. Daily number of hours of required assistance, either physical or supervisory.
Attention/Concentration
- The ability to focus on a given task or set of stimuli for an appropriate period of time.
Audiologist
- One who evaluates hearing defects and who aids in the rehabilitation of those who have such defects.
Augmentative and Alternative Communication
- Use of forms of communication other than speaking, such as: sign language, "yes, no" signals, gestures, picture board, and computerized speech systems to compensate (either temporarily or permanently) for severe expressive communication disorders.
Many thanks to HDI publishing for allowing us to include a portion of their Brain Injury Glossary. The complete Glossary contains over 800 terms and definitions. HDI offers a range of literature on the many and varied aspects of TBI such as family issues, life care planning, sexuality, coping, prevention, and education.
