Study Notes

Cluster Headaches

Characterized by short bursts of unilateral orbital pain.
Pain distribution follows the trigeminal nerve, featuring unilateral autonomic symptoms.
Symptoms include severe throbbing/stabbing pain, lacrimation, ptosis, and sweating.
Diagnosis is based on medical history and physical examination.
Treatment options include oxygen therapy and triptans for acute attacks, with preventive therapy using verapamil.

Seizure Disorders

Defined as transient physical or behavioral alterations due to abnormal brain electrical activity.
Epilepsy has specific definitions along with incidence and prevalence statistics.
Febrile seizures commonly occur in children.

Seizure Disorders: Clinical Manifestations

Seizures categorized into focal (simple/complex) and generalized types.
Generalized seizure types include absence, tonic, clonic, myoclonic, atonic, and tonic-clonic, with some unknown types.

Multiple Sclerosis (MS)

A chronic inflammatory, immune-mediated disease leading to demyelination and axonal degeneration in the central nervous system.
Genetic predisposition may contribute to MS development.
Theoretical mechanisms of demyelination involve immune system involvement.

MS: Clinical Manifestations

Features relapses and remissions, including sensory symptoms, visual disturbances, motor spasticity, and cognitive changes.
Other symptoms comprise bladder and bowel dysfunction, fatigue, and transverse myelitis.

Parkinson’s Disease

Characterized by neuron loss in the substantia nigra resulting in dopamine depletion.
Affects coordinated muscle movement through basal ganglia dysfunction.
Multiple cellular level abnormalities contribute to disease progression.

Parkinson’s Disease: Clinical Manifestations

Key symptoms encompass tremors, akinesia, rigidity, and postural instability.
Other motor dysfunctions include masked facial expression, micrographia, and speech difficulties.
Nonmotor symptoms may involve mood changes, cognitive decline, and dementia.

Amyotrophic Lateral Sclerosis (ALS)

Involves damage to motor neurons in the cerebral cortex, brainstem, and spinal cord.
Early signs include foot drop, lower extremity weakness, hand weakness, and dysarthria.
Symptoms in older children and adults can present as headaches, nausea, and balance issues.

Spina Bifida

Second most common birth defect in the U.S., classified as a neural tube defect.
Severity varies, with different forms including spina bifida occulta, meningocele, and myelomeningocele.
Surgical intervention is necessary for meningocele and myelomeningocele cases.

Cerebral Palsy (CP)

Nonprogressive disorders arising in early childhood affecting motor movement and coordination.
Resultant from brain abnormalities or damage to the cerebellum.
Risk factors include prematurity, low birth weight, and hypoxia.

CP: Clinical Manifestations

Movement disorders categorized into spastic, dyskinetic, and ataxic subtypes.
Development assessed via reflexes, motor tone, and posture.

Meningitis

Inflammation of the meninges, often due to infection.
Symptoms resemble influenza; diagnosis includes throat cultures, lumbar puncture, and imaging.
Treatment typically involves antibiotics, antivirals, and hydration management.

Encephalitis

Brain inflammation, often from infection, featuring flulike symptoms.
Diagnosis uses physical exams, imaging, and lumbar puncture.
Supportive treatment is the primary strategy, coupled with preventive measures.

Zika Virus Disease

A flavivirus primarily transmitted by mosquitoes, presenting flulike symptoms.
Diagnosis based on medical history and body fluid analysis.
Supportive treatment is essential; prevention is crucial.

Brain Injuries

Caused by blunt force trauma or penetrating wounds.
Disrupts normal brain function with varying complications.
Two main types: closed and open injuries.

TBIs: Clinical Manifestations

Symptoms can develop slowly or suddenly; Glasgow Coma Scale assesses severity.
Neurobehavioral changes indicate disruptions in consciousness levels (coma, vegetative state).

Increased Intracranial Pressure (ICP)

Result of increased cranial cavity fluid or tissue volume inconsistencies.
The Monro-Kellie hypothesis explains pressure-volume relationship affecting ICP and cerebral perfusion.
Compensation mechanisms exist and herniation can be a severe complication.

ICP: Clinical Manifestations

Symptoms vary by age; include decreasing consciousness, vomiting, elevated blood pressure, bradycardia, and fixed, dilated pupils.
Infants show separated sutures and bulging fontanelles; children/adults exhibit severe headaches and lethargy.

Hematomas

Blood collections due to ruptured vessels, classified as epidural, subdural, intracerebral, and subarachnoid.
Diagnosis involves patient history, physical examination, and imaging techniques.
Surgical removal is often necessary for treatment.

Spinal Cord Injuries (SCIs)

Result from direct spinal cord trauma or indirect damage to adjacent structures.
Primary (immediate) and secondary injuries may occur, often leading to edema and spinal shock.

SCIs: Clinical Manifestations (1 of 2)

Significant neurological loss includes flaccid paralysis and loss of sensation.
Neurogenic shock manifests with vasodilation and loss of sympathetic tone.

SCIs: Clinical Manifestations (2 of 2)

Autonomic dysreflexia results in unregulated heart rate and vascular responses.
Severity of dysfunction is determined by injury level, with classification according to ASIA standards.

Cerebral Vascular Accident (CVA) (1 of 2)

Interruption of cerebral blood flow, categorized as ischemic or hemorrhagic.
Ischemic strokes include thrombotic and embolic types; transient ischemic attacks (TIAs) present similarly but are temporary.

CVA: Clinical Manifestations (2 of 2)

Symptoms of ischemic strokes show sudden loss of focal brain functions, varying by the affected cerebral region.
Diagnosis relies on detailed history, physical examination, and imaging to differentiate stroke type.

CVA: Treatment

Early intervention is crucial; ischemic strokes are treated with thrombolytics and potential surgical procedures.
Hemorrhagic strokes need surgical repair to address aneurysms or malformations.

Cerebral Aneurysm

Defined as localized arterial outpouching in the brain, often asymptomatic until ruptured.
Diagnosis includes CT, MRI, and cerebral arteriography; medical repair is necessary upon rupture.

Arteriovenous Malformations (AVMs)

Marked by abnormal connections between arteries and veins, potentially causing hemorrhages and seizures.
Diagnosis utilizes imaging; treatment may involve excision or focused radiation therapy.

Migraine Headaches

Severe, debilitating headaches linked to systemic symptoms, categorized as migraine with or without aura.
Caused by waves of neuronal and glial depolarization, leading to neurogenic inflammation.

Migraine: Clinical Manifestations

Prodromal symptoms may include irritability and cravings; visual and sensory auras can occur.
Characterized by throbbing pain, nausea, vomiting, photophobia, and phonophobia.

Tension-Type Headaches

Result from nerve hypersensitivity; can be episodic or chronic.
Typically mild to moderate, described as dull or tight sensations.
Diagnostic approach involves medical history, while treatment includes NSAIDs and other analgesics.
