Different?Carol Ann Smith, RN, CNRNProgram Coordinator - Traumatic Brain Injury CenterDonna Lindsay, MN, RN, SCRNProgram Coordinator - Hennepin Stroke Center

Objectives

At the end of this presentation the learner will be able to: Define traumatic brain injury (TBI) and

stroke Describe similarities in TBI and stroke

neurological & functional impairments Identify differences in TBI and stroke

prevention

Definition

  TBI and Stroke are both types of acquired brain

injury Acquired brain injury is damage to the brain that

occurs after birth The two main types of acquired brain injury are:

Traumatic brain injury▪ Direct or indirect trauma to the brain

Non-traumatic brain injury▪ Includes brain damage from stroke, brain tumors, infection, hypoxia or substance abuse

Definition  In both TBI and Stroke, brain injury is often

categorized as primary or secondary Primary brain injury occurs at the time of the

initial insult to the brain (trauma, hemorrhage or infarct) Secondary injury occurs over hours to days

and involves an array of cellular processes that may be the result or independent of the primary insult Common causes of secondary brain injury are impaired

cerebral perfusion, altered brain metabolism & oxygen utilization, increased intracranial pressure, cerebral edema, seizure activity, electrolyte abnormalities and hypoxemia

Stroke Definitions

The rapid loss of brain function due to disturbance in the blood supply to the brain

Stoppage of blood flow to brain: a sudden blockage or rupture of a blood vessel in the brain

A stroke or "brain attack" occurs when a blood clot blocks an artery or a blood vessel breaks, interrupting blood flow to an area of the brain

Traumatic Brain Injury Definitions Traumatic Brain Injury (TBI) is caused by a blow

or jolt to the head or a penetrating head injury that disrupts the normal function of the brain Mild TBI ▪ a pathophysiological process affecting the brain induced by

direct or indirect biomechanical forces ▪ GCS 14-15

Severe TBI ▪ CT scan shows bleeding, bruising, shear injury, swelling▪ Major changes in blood flow & how the brain uses oxygen▪ Unconscious, GCS score 3-8

Stroke Statistics

Approximately 795,000 Americans suffer a stroke each year

Stroke is the 4th leading cause of death and the leading cause of serious, long-term disability in the US.

The cost of stroke in the US is approximately $28.6 billion annually.

On average in the US, every 40 seconds someonehas a stroke and every 4 minutes someone dies.

87 % of all strokes are ischemic, 10 % areintracerebral hemorrhage, and 3 % aresubarachnoid hemorrhage.

Stroke Statistics in MinnesotaOver 97,000 Minnesotans have had a

strokeApproximately 11,500 new strokes

occur each yearStroke is the 5th leading cause of

death and the leading cause of long-term disability

In 2011, $414 million was spent on hospital care for stroke

TBI Statistics According to research from CDC, approximately

3.5 million persons have a TBI in the United States each year. 2.1 million receive care in emergency departments, 300,000 are hospitalized, 84,000 are seen in outpatient departments, 1.1 million receive care from office-based

physicians, 53,000 die▪ TBI is a contributing factor to a third (30.5%) of all injury-

related deaths An Estimated $76.5 billion in direct medical costs

and indirect costs such as lost productivity due to TBI each year

5.3 million Americans living with long term disability

TBI Statistics in Minnesota 14,548 Minnesotans sustained traumatic brain

injury in 2012: (MDH - MIDAS) 10,310 were discharged from the emergency department 3.960 were hospitalized 278 died 58% male and 42% female This only counts people who present to the ED

Over 100,000 Minnesotans live with a disability as a result of a brain injury

83% of offenders entering the Minnesota prison system have a history of TBI

Non-fatal TBI in Minnesota

Types of Stroke Ischemic

Atherothrombotic Embolic Transient Ischemic

Attack

Hemorrhagic Intracerebral

Hemorrhage Subarachnoid

Hemorrhage

Types of Traumatic Brain Injury Brain injuries can be classified as:

Mild, moderate or severe▪ As determined by the Glasgow Coma Scale

Open or Closed▪ Skull fracture or no skull fracture▪ Linear, depressed, basilar▪ Penetrating wound (knife, bullet or other object)

Focal or diffuse▪ The injury is localized to one area (focal)▪ Hematoma, contusion

▪ The injury is throughout the entire brain (diffuse)▪ Concussion, shear injury

Types of TBI

ConcussionContusionEpidural HematomaSubdural Hematoma Intraparenchymal BleedSubarachnoid Hemorrhage Intraventricular HemorrhageDiffuse Axonal Injury (Shear)

What Causes Stroke?

Controllable Risk Factors High blood pressure (> 140/85 or if diabetic > 130/80)* High cholesterol (LDL > 130 if no other risk factors, >

100 if other risk factors present) Smoking* Atrial Fibrillation Heart Disease ( dilated cardiomyopathy, heart valve

disease, artificial heart valve, heart failure) Carotid Artery Disease Diabetes*

What Causes Stroke? Controllable Risk Factors (cont.)

Alcohol and Substance Abuse* Physical Inactivity Sleep Apnea Clotting Disorders* Vasculitis*

Uncontrollable Risk Factors Age (every decade over age 55 the risk of ischemic stroke doubles) Gender (men are at slightly higher risk) Race/Ethnicity* Family History* Vascular Abnormality*

* Risk factor for both hemorrhagic and ischemic stroke

How Do You Prevent Stroke? It is believed that 80 – 85% of ischemic

strokes could be prevented if risk factors were identified and controlled

Challenges to stroke prevention Lack of healthcare screening (risk factors

not identified) Failure of patients to adhere to risk

reduction measures Failure of healthcare providers to

implement aggressive risk reduction measures

How Do You Get a TBI? Etiologies:

Falls (35.2%)▪ Leading cause of TBI▪ Rates highest in children 0-4 & elderly > 75

Motor Vehicle Collision (17.3%) ▪ Results in greatest # of hospitalizations▪ Rate highest in 15-19 age group

Struck by/fell against (16.5%)

How Do You Get a TBI?

Assault (10%)▪ Firearm use leading cause of death related to

TBI▪ Blasts leading cause of TBI for active duty

military personnel in a war zone

Unknown (0%) Other (7%) Bicycle/non-MV (3%) Suicide (1%

(Source CDC)

How Do You Prevent a TBI? The only known cure for brain injury is

prevention!! Protect your brain - always wear a helmet for sports and recreational

activities Purchase only consumer product safety commission (CPSC) certified

helmets Concentrate on driving - never talk on a cell phone or text while

driving Everyone buckle up every time – infant car seats, booster seats for

children under 8 or under 40 lbs, then seat belts Stay focused & have a clear mind, do not drive impaired by drugs or

alcohol Stay steady - prevent falls from ladders and steps. Never shake a baby, never Keep small children away from open/screened windows and stairs Prevent falls in the elderly

Home safety evaluations, medication & vision checks

How Do You Manage Ischemic Stroke? Acute Stroke Treatment

Minimize secondary brain injury▪ Allow “permissive hypertension” for first 24-48 hours▪ Maintain Normothermia▪ Decompressive craniotomy/ICP management if edema is severe

Avoid complications (swallow screening and if needed modified diet, VTE prophylaxis, early mobilization, fall prevention)

Initiate rehabilitation therapies Diagnostic work-up to identify cause of stroke and

stroke risk factors Implement stroke risk factor reduction measures

How Do You Manage Hemorrhagic Strokes?

Intracerebral Hemorrhage Most common type of hemorrhagic

stroke Mortality rate is 35 – 55% Emergent reversal of INR if

anticoagulated Decompressive craniotomy, hematoma

evacuation Minimize secondary brain injury (similar

to TBI) Avoid complications Initiate rehabilitation therapies

How Do You Manage Hemorrhagic Strokes?

Subarachnoid Hemorrhage (non-traumatic) Mortality rate is approximately 50% (15% die prior

to reaching medical attention) Treat the underlying cause▪ 80% of SAH is caused by ruptured aneurysm▪ Surgical clipping or endovascular therapy

▪ 5% is caused by arteriovenous malformation▪ Endovascular therapy, radiosurgery and/or craniotomy

Prevent/manage secondary brain injury (vasospasm, hyponatremia)

Avoid complications Initiate rehabilitation therapies

How Do You Manage Hemorrhagic Strokes?

Treatment of Aneurysm - Clipping

Treatment of Aneurysm - Coiling

How Do You Manage Hemorrhagic Strokes?

Treatment of Aneurysm – Pipeline Stent

How Do You Manage Hemorrhagic Strokes?

Dysphagia Management▪ May require long-term or permanent feeding

tube and enteral nutrition Depression Management Promote Socialization (social-isolation is

common) Seizure Management ▪ prophylactic anticonvulsants are not

recommended

How Do You Manage Severe TBI?- For people who have a severe TBI:

Intracranial hypertension 40-50% Multiple injuries 50% Surgical mass lesion 40-50%

Mortality 30-35%

How Do You Manage Mild TBI?

At least 75% of TBI are mild CT usually “negative” Patient usually alert and oriented Range of symptoms that may or

may not involve LOC Manage the symptoms

Definition of Mild TBIA patient with mild traumatic

brain injury is a person who has had a traumatically induced physiological disruption of brain function, as manifested by a least one of the following:

any period of loss of consciousness; Only 10% lose

consciousness any loss of memory for

events immediately before or after the accident; ▪ Anterograde and/or▪ Retrograde

focal neurological deficit(s) that may or may not be transient;

any alteration in mental state at the time of the accident (eg, feeling dazed, disoriented or confused);

but where the severity of the injury does not exceed the following: Post-traumatic amnesia (PTA)

not greater than 24 hours. after 30 minutes, an initial

Glasgow Coma Scale (GCS) of 13-15; and

loss of consciousness of approximately 30 minutes or less;

 

Mild TBI Symptoms Cognitive

Feeling confused Dazed, foggy Amnesia Memory impairment Trouble concentrating Trouble with math Trouble finding the right

word to say

Affective Irritability Emotionally labile Feeling anxious Feeling depressed

Somatic Headache Dizziness, vertigo Nausea Tinnitus Double or blurry vision Insomnia/sleep

disturbances, fatigue Sensory disturbances,

phono &/or photophobia

Mild TBI Management Initial Treatment is Symptomatic:

Time & Rest Treat headache Treat nausea & vomiting Dark room/sunglasses for photophobia Quiet for phonophobia and headache No sleep medication (especially Ambien) No video games, excessive TV watching, texting If it causes symptoms, don’t do it

Mild TBI Management – Sent Home from ED

Rest, especially if you have any of the symptoms listed

Do not do any physical work or exercise until your symptoms go away. Anything that causes you to sweat is too much activity.

It is recommended that you see your family doctor within 2 weeks. Do not drive until your family doctor has told you it is okay to drive.

You should not work until you have not had any symptoms for 1 week.

Mild TBI Management – Sent Home from ED

If you go back to work and your symptoms come back and don’t go away for more than a week:▪ Stop working ▪ Go home▪ Call the HCMC TBI clinic for an appointment ▪ Do not go back to work until you have seen a

TBI clinic doctor Do not use alcohol (beer, wine, hard liquor) for

at least 2 months after your TBI. Do not play any sports until you have not had

any symptoms for at least 1 month.

Mild TBI - When do you need a Comprehensive TBI Clinic? The natural evolution of concussion is that

80% of the people will be back to their usual baseline within a month

Someone still experiencing symptoms after 4 weeks should be evaluated at a comprehensive TBI Clinic

Students should be seen at 2-3 weeks if having problems in school

Evaluation at a Comprehensive TBI Clinic Management based on history, social situation and

physical examination: Patient history & subjective complaints Review of medical records from TBI Patient Education▪ Natural History of TBI & Expectations for Recovery

Potential Referrals:▪ Neuropsychological testing▪ Speech Language Pathology▪ Occupational Therapy

▪ Vision Therapy▪ Physical Therapy▪ Clinical Psychology▪ Therapeutic Recreation▪ Vestibular clinic

Medications for headache, nausea, sleep

TBI Rehabilitation/Post-Acute Management

Severe TBI rehab similar to stroke

Mild TBI rehab focuses on treating the symptoms. Examples include: Energy Management and Relaxation Vestibular Management▪ Balance & Coordination▪ Epley Maneuver

Neuro Visual Rehab Cognitive & Linguistic Rehab Management of headache & other somatic symptoms Working with employers & schools on accommodations

Resources – MN Concussion Law Legislation on Concussion & Youth Sports signed into law June

2010 and took effect September 2011 Most comprehensive legislation in the nation

The goal of this new law is to improve the recognition and response of youth concussion injuries within all statewide youth athletic activities. This is the most comprehensive legislation in the country.

The Minnesota law applies to all players under the age of 18 and applies to ALL youth sports organizations both PUBLIC and PRIVATE. The law requires that parents have access to information on the risks and symptoms of concussions and coaches must have training on concussions once every 3 years.

The entire text of law can be seen online at the MN Legislature website https://www.revisor.mn.gov/laws Chapter 90, Senate File 612.
