INTRODUCTION
• Three of the top 15 causes of death in 2007
were neurologic in nature.
– Prevalence: number of people in a given
population with a particular disease
– Incidence: number of people diagnosed with a
particular disorder in a one-year period

Nervous SystemNervous system defined as:- Allows for communication
between cells through sensory input, integration of data,
and motor output.
2 cell types: neurons and neuralgia
2 divisions:
Central nervous system (CNS): Brain and spinal cord.
Peripheral nervous system (PNS): Nerves and ganglia
(cell bodies).
![Page 5: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/5.jpg)
Structure of the Nervous System
Each neuron contains:
1.Cell body: with nucleus.
2.Dendrites : fibers that receive messages from other neurons.
3.Axons : fibers that send messages to other neurons.
4. Axon Terminals:
–Transmit information

Neurons and Impulse Transmission
Synapses: slight gap between each cell.
Neurotransmitters: connects synapse to next cell.– Relay electrically conducted signals

Nervous System Organization
1. Central Nervous System (CNS)– Spinal Cord – simple decisions & information transmission.– Brain – “complex” decisions.
2. Peripheral Nervous System (PNS) Somatic Nervous System: the nerves that convey messages from
the sense organs to the CNS and from the CNS to the muscles and glands (voluntary movement).
Autonomic Nervous System: neurons that control the heart, the intestines, and other organs (involuntary movement).
• Sympathetic : increases ( HR, RS, B/P) acts in emergency as fear and anxiety.• Parasympathetic: decrease (HR, RS, B/P) acts in rest as
diet, and elimination.

Central Nervous System (CNS) Brain
Lobes
1. Occipital lobe: scans through images.
2. Temporal lobe: attaches image to name.
3. Frontal lobe: controls voluntary motion.
4. Parietal lobe: perceives touch and pain.
1.Cerebrum : largest part of human brain.
- Responsible for:
A. Thought
B. Language

Spinal cord The Spinal Cord: part of the CNS found within the spinal column.
The spinal cord communicates with the sense organs and muscles below the level of the head.
• 31 pairs & their branches• carries messages to & from the spinal cord• Both sensory and motor nerves

![Page 14: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/14.jpg)
Common Types OF Headaches
Head /ache defined as: Pain of head.
1. Tension headaches:• Stress causes residual muscle contractions.• Pain is generally felt on both sides of the head.• Usually a dull ache or a squeezing pain.
2. Migraine headaches: Caused by changes in the size of blood vessels at
the base of the brain. Pain is generally unilateral and focused.
Types of headache
![Page 15: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/15.jpg)
Common Types of Headaches
3. Cluster headaches
– Begins as minor pain around one eye and spreads
to one side of the face.
– 30–45 minutes each
4. Sinus headaches
– Inflammation /infection within sinus cavities.
– Pain is located in superior portions of the face.
–May be accompanied by postnasal drip, sore
throat, and nasal discharge.
![Page 16: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/16.jpg)
Management of Headaches
1. Maintain life style as diary food.2. Medications (purpose, side effects)
3. Stress reduction
Dark quiet room, relaxation
4. Regular exercise
5. Treat for trauma or injury if present.
6. Ask what medications patient has taken for pain
management:
• Ketofen and Morphine.
• Medication for nausea and vomiting
• Oxygen as needed.
![Page 17: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/17.jpg)
Intracranial Pressure (ICP) defined as: is the
pressure do by brain tissue, blood volume & cerebral spinal fluid (CSF) within the skull.
• Normal ICP is 0-15 mmHg (averages 10-15)• Brain, Blood, Cerebral Spinal Fluid are factors of
ICP.• When ICP increases, blood perfusion to brain
decreases.
Intracranial pressure
![Page 18: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/18.jpg)
1. LOC = decrease awareness of self & environment, confused, drowsiness, restlessness
2. hypoxia and acidosis.3. Motor cortex: hemiparesis.4. Cushing’s Triad: decrease pulse, Elevation of blood
pressure , and slow deep respirations (Life threatening signs)
5. Headache--increases in severity with coughing, sneezing,
6. Abnormal reflexes, vomiting 7. Pupil changes ( dilated pupil)
Signs & symptoms
![Page 19: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/19.jpg)
1. Monitor vital signs.2. Maintain patent airway. ( used intubation)If patient is not incubated, put the patient on hisone side to decrease the possibility of airwayobstruction.3. Be aware that stimulation of coughing whensuctioning increases intracranial pressure and mayprecipitate seizure activity. 4. Administer medications as ordered and
antibiotic.
Nursing Management
![Page 20: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/20.jpg)
5. Elevate head of bed (30º) ( semi flowers position to Promotes return of venous blood.
6. Fluids will be restricted to reduce intracranial pressure.
7. Accurate intake and output must be records.8. Protect patient from injury should as bed
side rails. 9. Secure a tongue blade to the head of the bed
for easy access. 10.Maintain normal body temperature.
Nursing Management

Stroke Stroke defined as: Disruption of blood flow in brain
May be leading to death.
Hemorrhage: bleeding in brain, blood vessel ruptures
can be from traumatic injury to blood vessel or
“aneurysm” weakening of blood vessel wall, balloon like
And rupture.
Causes: infections, toxins, Smoking, developmental
abnormality.

1. Health history:– Note speech, behavior, coordination, alertness, LOC.
2. Chief complaint and history of present illness:– Document what complain the patient to seek medical
attention– Describe any injuries. – If patient has pain, note the onset, severity, location,
and duration. 3. Past medical history:– Head injury, seizures, diabetes mellitus, hypertension,
heart disease, and cancer – Record dates and types of immunizations
Nursing Assessment of Neurologic Function
![Page 24: Care of Patient with neurological Disorder 2015 - 2016](https://reader036.vdocuments.net/reader036/viewer/2022070415/5697c02b1a28abf838cd87eb/html5/thumbnails/24.jpg)
4. Family history:
– Have immediate family members had heart disease,
stroke, diabetes mellitus, cancer, seizure disorders?
5.Review of systems:
– Fatigue or weakness, headache, dizziness, changes in
vision / hearing, drainage from ears or nose, neck pain or
stiffness, vomiting, bladder or bowel function, sexual
dysfunction, fainting, tremors, paralysis, in coordination,
numbness, memory problems, mood changes.
Nursing Assessment of Neurologic Function

1. Ineffective airway clearance related to decreased protective reflexes (cough, gag)
2. Ineffective cerebral tissue perfusion related to the effects of increased ICP.
3. Knowledge defect related to disease.
4. Fatigue and restlessness related to complication of disease.
5. Activity introlance related to complication of disease.
