Study Notes
Headaches - Etiology and Pathophysiology
- Recurring headaches require thorough physical examinations and neurological assessments to identify the source.
- Head pain arises from the scalp, blood vessels, muscles, dura mater, and venous sinuses; the brain itself cannot feel pain.
- Headaches are classified into vascular, tension, and traction-inflammatory types:
- Vascular headaches: Includes migraine, cluster, and hypertensive headaches.
- Tension headaches: Can stem from emotional stress or medical issues like cervical arthritis.
- Traction-inflammatory headaches: Caused by infections, intracranial or extracranial issues, and temporal arteritis.
- Migraines predominantly affect individuals aged 10-45 years, often with accompanying auras such as visual disturbances or sensory anomalies.
- Tension and cluster headaches have distinct symptoms and triggers, with cluster headaches occurring in cyclical patterns.
Headache Assessment
- Subjective Data: Patient's perception of headaches, possible causes, symptom relief measures, pain characteristics, associated symptoms, allergies, and family history.
- Objective Data: Behavioral signs of pain or stress, changes in daily activities, abnormal vital signs, and physical examination findings are important.
Diagnostic Tests
- Non-transient headaches should be evaluated through neurological examinations, CT scans, MRIs, brain scans, skull radiographs, and, in some cases, lumbar punctures (with caution regarding ICP).
Medical Management
- Dietary changes can mitigate headache severity; foods high in tyramine (aged cheeses, cured meats) and nitrites (processed meats) may trigger headaches.
- Psychotherapy may help patients manage stress related to headaches.
- Mild migraines often respond to OTC medications like aspirin, acetaminophen, or ibuprofen, but should not be used excessively to avoid rebound headaches.
- Triptans are first-line treatment for more severe migraines and work by constricting dilated cranial blood vessels.
Cluster Headaches
- Characterized by intense unilateral pain, often accompanied by tearing and nasal congestion, occurring daily for weeks followed by remission periods.
- Diagnosis is primarily based on clinical symptoms, including Horner’s syndrome during attacks.
- Opioids may be used for severe pain relief.
Tension Headaches
- Treated with nonopioid analgesics like acetaminophen and ibuprofen; opioids are generally avoided to prevent dependence.
Nursing Interventions and Patient Teaching
- Stress management, relaxation techniques, and a quiet environment are vital for patients.
- Comfort measures like cold packs and dark environments for migraine sufferers can aid symptom relief.
- Identifying headache triggers (fatigue, stress, allergies) through diaries or assessments can guide lifestyle modifications.
Prognosis
- With effective management, individuals can maintain a normal lifestyle despite periodic headaches, though chronic headaches can significantly affect quality of life.
Neuropathic Pain Overview
- Neuropathic pain results from direct stimulation of the nervous system, characterized by tingling or burning sensations.
- Common causes include diabetic neuropathies and postherpetic neuralgia.
Assessment of Neuropathic Pain
- Subjective data includes patient self-reporting on pain, coping strategies, and responses to triggers.
- Objective data focus on behavioral indicators of pain, changes in activity levels, and sensory examination findings.
Diagnostic Tests for Neuropathic Pain
- Potential tests include electrical stimulation and myelograms in cases of back/neck pain.
Medical Management of Neuropathic Pain
- Non-surgical methods include transcutaneous electrical nerve stimulation and acupuncture.
- Medications like anticonvulsants (gabapentin, carbamazepine) and antidepressants (amitriptyline) are effective for controlling pain.
- Opioids may have limited effectiveness.
Nursing Interventions for Neuropathic Pain
- Patients should be assisted in finding comfortable positions and provided with dietary support to prevent exacerbation of pain.
- Promoting rest and understanding triggers are essential components of care.
Prognosis for Neuropathic Pain
-
Adequate treatment can lead to improved quality of life, though chronic pain often requires lifestyle adaptations.### Increased Intracranial Pressure (ICP)
-
CT and MRI have transformed the diagnosis and treatment of increased ICP, which is often a medical emergency.
-
Diagnostic tests for increased ICP include ICP measurement, EEG, cerebral angiography, transcranial Doppler studies, and PET.
-
Lumbar puncture is contraindicated in suspected increased ICP due to the risk of cerebral herniation.
-
Internal monitoring devices such as a hollow screw may be implanted in the skull to assess ICP continuously.
Medical Management
- The primary objective is to treat the underlying cause of increased ICP while preventing further elevation.
- Surgery may be necessary for causes like tumors; if surgery is not possible, drug therapy is employed.
- Oxygenation is crucial, with arterial blood gas analysis guiding oxygen therapy.
- Controlled ventilation can lower PaCO2, reducing vasodilation and ICP.
- Mechanical decompression options include craniotomy, craniectomy, and ventricular drainage.
Monitoring Systems
- Basic ICP monitoring systems include ventricular catheters, subarachnoid bolts, and epidural sensors, all of which detect pressure waves.
Medications
- Osmotic Diuretics: Such as mannitol, draw fluid from brain tissue and show effects within 15 minutes.
- Loop Diuretics: Like furosemide and bumetanide may assist in managing ICP.
- Corticosteroids: Historically standard treatment but now used with caution due to associated increased mortality rates. They necessitate close monitoring of blood glucose levels.
- Anticonvulsants: Prevent seizures in patients with increased ICP.
Nursing Interventions
- Elevate head of the bed to 30-45 degrees to enhance venous return.
- Maintain neutral neck positioning to support drainage; avoid flexion at joints that can increase ICP.
- Limit activities that increase thoracic pressure, which can lead to increased ICP.
- Manage fluid intake and prevent the Valsalva maneuver.
- Oxygen therapy should be administered via mask or cannula to improve cerebral perfusion.
Prognosis
- Prognosis varies based on the cause of ICP and speed of intervention.
- Delayed treatment following brain herniation typically results in irreversible brain damage.
Motor Function Disturbances
- Motor dysfunction is often observed in patients after neurological damage, affecting mobility like in cerebral palsy.
- Muscle tone can be flaccid or hyperreflexic, with symptoms varying based on lesion location.
Assessment
- Collect subjective data on symptom onset and impact on daily life while noting mobility and strength through objective data.
- EMG testing is vital for diagnosing pathologies in muscle function.
Medical Management
- Baclofen and similar muscle relaxants are prescribed for spasticity with side effects including drowsiness.
- Thorough assessments for swallowing difficulties are crucial, as aspiration risk is high.
Nursing Care for Patients with Motor Problems
- Implement safety measures, including the use of side rails and fall precautions.
- Regularly check skin integrity, particularly over bony prominences, to prevent pressure ulcers.
- Assist with activities of daily living and provide adaptive equipment for independence.
Nutritional and Psychological Considerations
- Patients may struggle with significant nutritional intake and require dietary modifications.
- Psychological support is essential as patients adjust to loss of function and may experience grief and fear about the future.
Education and Teaching
- Provide thorough patient and family education on safety, care, medication management, nutrition, and follow-up care to promote independent living and rehabilitation.
Neurological Disorders Overview
- Neurological conditions create physical and cognitive challenges, affecting mobility, coordination, and sensory perception.
- Assess and support all patterns of functioning, including sleep, cognition, and coping mechanisms to optimize patient care.### Assessment of Sensory Disturbance

Medical Management
- Treatment is based on the underlying cause of altered muscle tone and motor function.
Nursing Interventions & Patient Teaching
- Educate patients on protective measures for body parts with sensory loss.
- Encourage regular inspection of areas without feeling to prevent injury.
- Teach compensatory techniques for deficits in one sense (e.g., lip-reading for hearing loss, scanning for vision deficits).
