3、 considered the computer of the human body. It is enclosed inside the bony skull, which acts as a protective covering. On the inside of the body, it is protected by the blood-brain barrier, a protective barrier that keeps out toxic substances and allows fat (lipid) soluble substances through.,4,THE

4、HEALTHY BRAIN,The basic functional unit of the brain is the neuron, a cell that is specialized to send information. The brain uses these neurons to communicate with other parts of the brain, the spinal cord and ultimately with the rest of the body. Movement, cognition and emotional expression are ju

5、st some of the functions. There are 100 billion of these in the normal brain. The parts of the neuron are: Cell body Maintenance of cell life Nutrition, waste removal, manufacturing of chemicals Dendrite Receive information from other cells or stimuli Up to 10,000 in one cell Axon Main pathway to ot

6、her cells Usually one main axon Myelin Protective wrapping around cells Speeds nerve impulses,5,THE HEALTHY BRAIN,Drawing of a neuron,6,THE BRAIN IS DIVIDED INTO LOBES, THE CEREBELLUM AND THE BRAIN STEM,7,THE HEALTHY BRAIN,The Frontal Lobe is involved in the following functions: Initiation Problem s

11、Brain Injury Source: Brain Injury Association of New York State www.bianys.org,The majority of people are injured in car accidents. It is important to note that you do not have to be traveling at a high rate of speed to get a head injury. Nor do you have to hit your head on an object (steering wheel

12、, windshield) to injure the brain. Even at moderate rates of speed, traumatic brain injuries can and do occur,12,TRAUMATIC BRAIN INJURY (TBI),TRAUMATIC BRAIN INJURY (TBI) is an insult to the brain, not of a degenerative or congenital nature but caused by an external physical force, that may produce

13、a diminished or altered state of consciousness, which results in an impairment of cognitive abilities or physical functioning. These impairments may be either temporary or permanent and cause partial or total functional disability or psychosocial maladjustment. *Brain Injury Association, 1986,13,ACQ

14、UIRED BRAIN INJURY (ABI),The term Acquired Brain Injury refers to TBI, as well as other types of brain injuries occurring after birth, such as stroke, near suffocation, infections in the brain, anoxia. TBI/ABI is not due to an inherited, degenerative or congenital problem. The effects of a brain inj

15、ury depend on the cause, the location of the injury and the severity of the injury. Brain injury is an invisible disability.,14,TRAUMATIC BRAIN INJURY,Traumatic brain injury can cause death.,15,ACQUIRED BRAIN INJURY,Acquired brain injury can be due to trauma, such as an open or closed trauma, or due

16、 to infections, medical problems such as stroke or substance effects. Brain tumor Meningitis Seizure disorder Hepatic encephalopathy (seen in liver failure) Heart attack Anoxia Near drowning Choking Strangulation Electrical shock Lightening strike Exposure to toxins or chemicals CVA/Stroke Aneurysm

17、Alcohol and drugs,16,TRAUMATIC BRAIN INJURIES: OPEN AND CLOSED BRAIN INJURY,Open,Closed,MAY NOT BE AS APPARENT AS AN OPEN INJURY,17,LEVELS OF BRAIN INJURY,Mild TBI Loss of consciousness is very brief, usually a few seconds or minutes Loss of consciousness does not have to occur the person may be daz

18、ed or confused Testing and scans of the brain may appear normal Most common: 75%-85% of all brain injuries are mild 90% of individuals recover within 6-8 weeks, often within hours or days, but 10% experience deficits, which may not be evident immediately More than one mild brain injury over time (e.

19、g., sports injuries or domestic violence) increases the chance of deficits,18,LEVELS OF BRAIN INJURY,Moderate TBI Loss of consciousness lasts from a few minutes to a few hours Confusion lasts from days to weeks Physical, cognitive, and/or behavioral impairments last for months or are permanent EEG/C

20、AT/MRI are positive for brain injury,19,LEVELS OF BRAIN INJURY,Severe TBI Prolonged unconscious state or coma lasts days, weeks, or months Categories include: Coma Vegetative State Persistent Vegetative State Minimally Responsive State Locked-in Syndrome,20,LEVELS OF BRAIN INJURY,Severe TBI Categori

21、es Coma Unconscious state from which the individual cannot be awakened with minimal or no meaningful response to stimuli Vegetative State Arousal is present but cannot interact with environment Eye opening can be spontaneous or in response to stimulation Persistent Vegetative State Vegetative state

22、lasting for more than one month Minimally Responsive State No longer in coma or vegetative state with primitive reflexes and inconsistent ability to follow simple commands, though an awareness of the environment Locked in Syndrome Rare neurologic condition in which a person cannot physically move an

23、y part of the body except the eyes. The person is conscious and able to think.,21,GLASGOW COMA SCALE The Glasgow Coma scale provides an objective way to evaluate a patients level of consciousness and to detect changes from baseline functioning.,22,AN INJURED BRAIN,Changes are noted to thought proces

24、ses: Memory Decision making Planning Sequencing Judgment Attention Communication Reading and writing skills Thought processing speed Problem solving skills Organization Self perception Perception Thought flexibility Safety awareness New learning,23,AN INJURED BRAIN,Physical Changes are seen: Muscle

25、movement Muscle coordination Sleep Hearing Vision Taste Smell Touch Fatigue Weakness Balance Speech Seizures Sexual functioning,24,AN INJURED BRAIN,Personality and Behavioral Changes Social skills Emotional control and mood swings Appropriateness of behavior Reduced self-esteem Depression Anxiety Fr

26、ustration Stress Reduced Self Awareness (often misunderstood as denial) Self-centeredness Anger management Coping skills Self-monitoring remarks or actions Motivation Irritability or agitation Excessive laughing or crying,25,AN INJURED BRAIN,Right sided injuries Visual-spatial impairment Visual memo

27、ry deficits Decreased awareness of deficits Altered creativity and music perception Loss of “the big picture” type of thinking Decreased control over left sided body movements Left sided injuries Difficulties in understanding language (receptive language) Difficulties in speaking or verbal output (e

28、xpressive language) Depression Anxiety Verbal memory deficits Impaired logic Sequencing difficulties Decreased control over right sided body movements,26,ACQUIRED BRAIN INJURY,Alcohol and drugs can cause brain injury directly or indirectly. Alcohol is a neurotoxin, though its effect and extent of da

29、mage depends on the amount of alcohol consumption, the age and sex of the consumer, genetic vulnerability and other factors. Binge drinkers may be less prone to alcohol related cognitive deficits than heavy daily users, though they are still vulnerable to alcohol intoxication related events.,27,ACQU

30、IRED BRAIN INJURY,Alcohol can cause Direct brain damage (alcohol dementia, Wernicke Korsakoffs Syndrome, and atrophy of the cerebrum and cerebellum. There can be some improvement in deficits with abstinence Indirect damage can be associated with Falls and accidents Intracerebral bleeds due to alcoho

31、l effect on platelets and blood pressure Hepatic encephalopathy due to alcohols effect on the liver,28,ACQUIRED BRAIN INJURY,Solvents such as glue can lead to ataxia (impaired gait) and cognitive problems. Metabolic syndromes can also be seen especially with inhalation of substances that effect the

32、kidney. Cannabis dependence is associated with impaired attention, concentration and motivation,29,ACQUIRED BRAIN INJURY,Stimulant use can be associated with strokes (as seen here), seizures and long term memory and concentration problems.,30,ACQUIRED BRAIN INJURY,Sedative effects are not well studi

33、ed in the long term, though overdose can lead to respiratory compromise and oxygen deprivation. Oxygen deprivation can also be seen in opiate overdose as pictured here, where the overdose victim developed noncardiogenic pulmonary edema* and intubation and respirator care was needed.,* NONCARDIOGENIC

34、 PULMONARY EDEMA A Condition whereby the lungs fill up with fluid (PULMONARY EDEMA) but the cause is not heart failure (CARDIOGENIC) in origin, the usual cause of PULMONARY EDEMA is congestive heart failure, where the heart is not pumping properly and the blood backs up into the lungs.,31,The CDC es

35、timated that 5.3 million Americans live with disabilities due to brain injury and that 67% of people in rehabilitation for brain injury have a previous history of substance abuse (Thurman, 1998). 50% of these people will return to using alcohol and drugs after the injury (Corrigan, 1995).,32,20% of

36、persons with brain injuries who did not use alcohol or drugs prior to the injury, were vulnerable to alcohol and drug use after the injury (Corrigan, 1995). 50% of clients enrolled in OASAS Programs were affected by probable TBI (N=647) (Fenske, Gordon, Perez, Hibbard, Brandau, submitted for publica
