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.
