6. I. Neurological Disorders The normal functioning of the CNS can be affected by a number of disorders, the most common of which are headaches, tumors, vascular problems, infections, epilepsy, head trauma, demyelinating diseases, and metabolic & nutritional diseases.
7. Headaches Classified based on characteristics of the headache
Functional vs. Organic type
May have more than one type of headache
History & neurologic exam diagnostic keys
9. HA: Essential History Onset this particular headache
Character of pain, severity and duration
Associated symptoms
Prior history, pattern
Original onset: prior testing, treatment
Other therapeutic regimens
10. Physical Exam Neurologic examination
Inspect for local infections, nuchal rigidity
Palpation for tenderness, bony swellings
Auscultation for bruits over major arteries
11. Organic vs. Traumatic vs. Functional: Diagnostics CBC: underlying illness, anemia
Chem panel: if associated vomiting, dehydrated
CT scan: for focal neurological signs, sinus
No LP for suspected ICP; ? association with brain herniation
12. Don’t Miss It
13. Headache Teaching Guide Keep a calendar/diary
Avoid triggers
Medications (purpose, side effects)
Stress reduction

14. Intracranial Pressure (ICP) Brain Components
Skull is a rigid vault that does not expand
It contains 3 volume components:
Brain tissue: (80%) or 2% of TBW
Intravascualr blood: (10%)
CSF: (10%)
15. Intracranial Pressure (ICP) is the pressure exerted by brain tissue, blood volume & cerebral spinal fluid (CSF) within the skull.
ICV = Vbrain + Vblood + Vcsf
Normal ICP – 10 to 15 mmHg
Cerebral Perfusion Pressure (CPP)
CPP = MAP – ICP
Normal CPP – 70 to 100 mmHg
Normal CSF – 5 to 13 mmHg
Intracranial Pressure (ICP)
16. Increased Intracranial Pressure (IICP) fluid pressure > 15 mm Hg IICP is a life threatening situation that results from an ? in any or all 3 components within the skull
> volume of brain tissue, blood, and / or CSF
Cerebral edema: > H2O content of tissue as a result of trauma, hemorrhage, tumor, abscess, or ischemia
18. Acute Coma Levels of consciousness diminish in stages:
Confusion: can’t think rapidly and clearly ???????
Disorientation: begin to loose consciousness
Time, place, self
Lethargy: spontaneous speech and movement limited
Obtundation: arousal (awakeness) is reduced
Stupor: deep sleep or unresponsiveness
Open eyes to vigorous or repeated stimuli
Coma: respond to noxious stimuli only
Light (purposeful), full coma (non-purposeful), deep coma (no response)
19. 19 Multiple Sclerosis
is a chronic autoimmune disorder affecting movement, sensation, and bodily functions. It is caused by destruction of the myelin sheath covering nerve fibres in the central nervous system (brain and spinal cord).
Causes:
1. Autoimmune destruction.
2. Heredity.
3. Viruses.
4. Environmental factors.
20. 20 Diagnostic Test:
1. MRI.
2. Physical examination.
21. 21 * Early:
1. Muscle weakness causing difficulty walking
2. loss of coordination or balance
3. numbness or other abnormal sensations
4. visual disturbances, including blurred or double vision
Clinical Manifestations:
22. 22 * Late:
1. Fatigue .
2. Muscle spasticity and stiffness
3. Tremors.
4. Paralysis .
5. pain .
6. Vertigo.
7. Speech or swallowing difficulty .
8. Loss of bowel and bladder control.
9. Sexual dysfunction .
10. Changes in cognitive ability
23. 23 Treatment: 1. Immunosuppressant drugs . These drugs include corticosteroids such as prednisone and methylprednisolone, the hormone adrenocorticotropic hormone (ACTH), and azathioprine.
2. Physiotherapy.
3. Occupational therapy.
24. 24 Parkinson's Disease is a progressive movement disorder marked by tremors, rigidity, slow movements (bradykinesia), and postural instability. It occurs when, for unknown reasons, cells in one of the movement-control centers of the brain begin to die.
Causes:
1. Degeneration of brain cells in the area known as the substantia nigra, one of the movement control centers of the brain.
2. Drugs given for psychosis, such as haloperidol (Haldol) or chlorpromazine (Thorazine), may cause parkinsonism.
25. 25 Clinical Manifestations 1. Tremors
2. Slow movements (bradykinesia), freezing in place during movements (akinesia).
3. Muscle rigidity or stiffness, occurring with jerky movements
4. Postural instability or balance difficulty occurs.
5. Masked face.
6. Depression
7. Speech changes
8. Problems with sleep
9. Emotional changes10. Incontinence.
11. Constipation.
12. Handwriting changes,
13. (dementia)
26. 26 Treatment: 1. Maintain regular exercise (physical therapy, occupational therapy)
2. Provide good nutrition to maintain health.
3. Drugs that replace dopamine (levodopa)
4. If the patient is unresponsive or intolerant to pharmacotherapy, Electro convulsive therapy is indicated.
Nursing Management
* Observe the patient's mood, cognition; organization and general well being
* Observe for features of depression,
*Suicidal precautions to be followed, if the patient exhibits any suicidal ideas
*Instruct the patients to speak slowly and clearly, and to pause and take a deep breath at appropriate levels.
27. 27 Parkinson's Disease (cont’d) *In dementia, environmental modification is followed
*Avoid frequent change in the environment to minimise confusion if the memory deficit is very severe, name boards and signboards by the side of the rooms and things will be very helpful.
*Sedatives are used if sleep related problems are noticed, when sleep hygiene is unsuccessfully.
* Patients should not be forced into situations in which they feel ashamed of their appearance.
*Encourage the patient to participate in moderate exercises, free-moving sports like swimming.
*Advise the patient to organize thoughts before speaking and encourage the client to use facial expression and gestures if possible to assist with communication.
28. Seizure Disorders & Epilepsy Seizure:
paroxysmal, uncontrolled electrical discharge of neurons in the brain that interrupts normal function
Epilepsy:

Immediate head CT (check for blood)
Evaluate for tPA administration (review exclusion/inclusion criteria) CT does not show new stroke, need MRICT does not show new stroke, need MRI
46. Treatment Cont… If not a tPA candidate, ASA in ED. Rectal ASA if fails swallow eval. or if swallow eval. not complete.
Keep NPO, until a formal swallow eval. is done.
Admit as Inpatient and perform diagnostic testing: Carotid US, Echo, TEE, ECG monitoring for a-fib, MRI, fasting Lipid, Clotting disorder blood work (Antiphospholipid, Factor V, Antithrombin III)
