NEUROLOGICAL NURSING

Anatomy and Physiology

Page 2: My neurological nursing

Neurological Nursing

Purpose: To understand the workings and functions of the human nervous system.

To successfully identify disease processes common to the human nervous system.

To provide proficient care to individuals afflicted with disease processes or injuries affecting the human nervous system.

Page 3: My neurological nursing

Neurological Nursing

A & P of the Nervous System

Page 4: My neurological nursing

Neurological Nursing

Neuron- The functional unit (cell) of the nervous system that conducts electrical impulses to the brain and to other areas of the body.

Sensory Neurons- Carry information from the distal parts of the body toward the central nervous system (CNS)

Motor Neurons- Carry motor information from the CNS to the periphery.

Page 5: My neurological nursing

Neurological Nursing

Axon and dendrites branch off of the main body of the neuron.

Axon- Carry impulses away from the cell body

Dendrites – Carry impulses to the cell body.

Myelin- is a substance that sheaths many axons and dendrites. It enhances conduction along the nerve fiber (moves impulse very quickly) and gives the axons their white appearance.

Page 6: My neurological nursing

Neurological Nursing

The Central Nervous System (CNS)

Made up of the BRAIN and the SPINAL CORD

The Peripheral Nervous System (PNS)

Made up of all of the peripheral of the body, including the spinal and cranial nerves

Page 7: My neurological nursing

Neurological Nursing

Page 8: My neurological nursing

Neurological Nursing

The Brain is divided into the Cerebrum, Cerebellum and the Brain Stem.

Cerebral Spinal Fluid (CSF) is composed of water, glucose, sodium chloride and protein.

Its FUNCTION is that it acts as a shock absorber for the brain and spinal cord.

Page 9: My neurological nursing

Page 10: My neurological nursing

Neurological Nursing

The Spinal Cord

Extends from C1 to L2There are 31 pairs of spinal nerve roots that exit the spinal cord, each consisting of an afferent root (posterior sensory)and efferent root (anterior motor).These roots, along with the 12 cranial nerves make up the PERIPHERAL NERVOUS SYSTEM.

Page 11: My neurological nursing

Neurological Nursing

Autonomic Nervous System

Controls the INVOLUNTARY activities of the viscera including smooth muscle, cardiac muscle and glands

Two major subdivisions: The SYMPATHETIC NERVOUS SYSTEM (SNS) and the PARASYMPATHETIC NERVOUS SYSTEM (PNS).

Page 12: My neurological nursing

Cerebrum

Complex functions:

Initiation of movements, recognition of sensory input, higher-order thinking, regulating emotional behavior and endocrine and autonomic functions

Page 13: My neurological nursing

Cerebrum

Divided into two halves: hemispheres

Each hemisphere controls the opposite side of the body: the right hemisphere controls the left side of the body, and the left hemisphere controls the right side of the body

The cortex of each is divided into the parietal, frontal, temporal, and occipital lobes; each has a different area of function

Page 14: My neurological nursing

Cerebrum

Page 15: My neurological nursing

Cerebrum

Brainstem

Includes midbrain, pons, medulla, and part of the reticular activating system

Controls vital, basic functions, including respiration, heart rate, and consciousness

Page 16: My neurological nursing

Cerebellum

Uses information received from the cerebrum, muscles, joints, and inner ear to coordinate movement, balance, and posture

Unlike the cerebrum, the right side of the cerebellum controls the right side of the body, and the left side of the cerebellum controls the left side of the body

Page 17: My neurological nursing

Circulation

Carotid System

Begins as one common artery; later divides into the external and internal carotid arteries

The external carotid arteries divide to supply blood to the face

The internal arteries further divide into the middle cerebral artery and the anterior cerebral artery to supply blood to the brain

Page 18: My neurological nursing

Circulation

Carotid System

Begins as one common artery; later divides into the external and internal carotid arteries

The external carotid arteries divide to supply blood to the face

The internal arteries further divide into the middle cerebral artery and the anterior cerebral artery to supply blood to the brain

Page 19: My neurological nursing

Circulation

Vertebral Arteries

Originate from the subclavian artery, travel up the anterior neck to merge and form the basilar artery at the brainstem

Second division forms posterior cerebral artery

Internal carotid and vertebrobasilar arteries unite to form the circle of Willis

Page 20: My neurological nursing

Page 30: My neurological nursing

SEIZURE DISORDERS

Electrical impulses in the brain are conducted in a highly chaotic pattern that yields abnormal activity and behavior.

Related to trauma, reduced cerebral perfusion, infection, electrolyte disturbances, poisoning, or tumors.

Page 31: My neurological nursing

Page 109: My neurological nursing

Stroke

An abrupt impairment of brain function resulting in a set of neurologic signs and symptoms that are caused by impaired blood flow to the brain and last more than 24 hours

Page 110: My neurological nursing

Stroke

PathophysiologyHemorrhagic stroke

Blood vessel in brain ruptures; bleeding into the brain occurs

Ischemic stroke Obstruction of blood vessel by atherosclerotic

plaque, blood clot, or a combination of the two, or by other debris released into vessel that impedes blood flow to an area of the brain

Page 111: My neurological nursing

Stroke

Page 112: My neurological nursing

Stroke

Signs and Symptoms

Different signs and symptoms, depending on the type, location, and extent of brain injury

Hemorrhagic stroke Occurs suddenly; may include severe headache

described as “the worst headache of my life”

Other symptoms: stiff neck, loss of consciousness, vomiting, and seizures

Page 113: My neurological nursing

Stroke

Signs and Symptoms

Embolic stroke

Appear without warning

One or more of the following signs and symptoms: one-sided weakness, numbness, visual problems, confusion and memory lapses, headache, dysphagia, and language problems

Page 114: My neurological nursing

Age-Related Changes

The number of nerve cells decreases

Brain weight is reduced; ventricles increase in size

Lipofuscin: aging pigment deposited in nerve cells with amyloid, a type of protein

Increased plaques and tangled fibers in nerve tissue

Eye pupil often smaller; may respond to light more slowly

Page 115: My neurological nursing

Age-Related Changes

Sensory losses put patient at risk for traumatic and thermal injuries

Swallowing difficulties place patient at risk for pulmonary complications, such as choking and aspiration pneumonia

Page 124: My neurological nursing

Stroke

Prognosis

Prognosis for TIA or stroke increasingly hopeful

Critical variables for recovery: patient’s condition before the stroke, time between stroke and diagnosis, treatment and support in acute phase (usually the first 48 hours), severity of patient’s symptoms, and access to rehabilitative therapy

Page 125: My neurological nursing

Stroke

Prognosis

Long-term recovery may depend on the care received immediately after the stroke

Most recovery takes place in the first 3 to 6 months, but progress often continues long after that

Page 126: My neurological nursing

Stroke

Medical Treatment in the Acute Phase

Begins with the onset of signs and symptoms and continues until vital signs, particularly blood pressure and neurologic condition, stabilize

This phase usually lasts 24 to 48 hours Many medical management interventions are directed at minimizing complications and deterioration of the patient’s condition after a stroke

Page 127: My neurological nursing

Stroke

Medical Treatment in the Acute Phase

Major focus areas Hypertension Oxygenation Hyperthermia Hyperglycemia

Drug therapy Tissue plasminogen activator (rt-PA, alteplase,

Activase) Given to dissolve clots in acute ischemic strokes

Other Medications Mannitol Nimodipine (Nimotop) Phenytoin (Dilantin) and phenobarbital Acetylsalicylic acid (aspirin), ticlopidine

hydrochloride (Ticlid), Aggrenox, and clopidogrel (Plavix)

Page 129: My neurological nursing

Discharge

Patients may be discharged to home or go to specialized rehabilitation centers for continued therapy

Outpatient therapy is an option for some patients

When able, patients are transitioned back into the home setting

Essential to include family, friends, and significant others in this process

Page 145: My neurological nursing

Discharge

During and after the rehabilitation phase, patients and families need to be made aware of resources to help them deal with continuing disabilities

In rehabilitation, the patient is respectfully challenged to return to the highest level of function possible
