Study Notes
Cerebrovascular Conditions
- Symptoms: Sudden onset neurological symptoms (weakness, numbness, incoordination, facial droop, slurred speech, language difficulties, visual changes, headache). Headache might be a thunderclap in subarachnoid hemorrhage.
- Examination Findings: Focal neurological deficits, facial droop, limb weakness/numbness, aphasia (language impairment), ataxia.
- Differential Diagnosis: Hypoglycemia (mimics symptoms)
- Examples: Stroke (ischemic, hemorrhagic), Transient Ischemic Attack (TIA), cavernous sinus thrombosis, subarachnoid hemorrhage.
Demyelinating Conditions
- Symptoms: Visual changes (blurred vision, eye pain, optic neuritis, double vision, nystagmus), swallowing and speech problems (brainstem involvement), muscle weakness (spasms, tremors, ataxia), paralysis, numbness, paraesthesia. Symptoms worsen with heat. May have relapsing-remitting pattern. Autonomic dysfunction (constipation, incontinence, sexual dysfunction).
- Examples: Multiple Sclerosis (MS), Guillain-Barré Syndrome, Charcot-Marie-Tooth disease.
- Guillain-Barré Syndrome (GBS): Rapidly progressive, symmetric, ascending weakness in the distal lower extremities. Often preceded by a recent respiratory or gastrointestinal bacterial or viral infection (e.g., Campylobacter, mycoplasma, CMV, EBV).
- GBS Examination: Lower limb weakness, reduced deep tendon reflexes (lower limb), bilateral facial nerve palsy, diaphragm involvement (possible respiratory failure/shortness of breath), pharyngeal muscle involvement (swallowing impairment).
- GBS Autonomic Dysfunction: Blood pressure fluctuations, cardiac arrhythmias, sweating. Sensation is usually preserved.
Infectious Conditions
- Symptoms: Photophobia, nausea, vomiting, fever, headache, neck rigidity, Kernig sign, Brudzinski sign, papilledema.
- Examples: Meningitis, encephalitis, brain abscess.
Neurodegenerative Conditions
- Alzheimer's Disease (AD): Dementia (short-term memory loss, then long-term), loss of motor skills and language, sporadic (late onset) or familial (early onset, genetic).
- Parkinson's Disease (PD): Tremor, rigidity, bradykinesia (slow movement), postural instability, depression, dementia, sleep disturbance, anosmia (loss of smell).
- Huntington's Disease (HD): Chorea (involuntary movements), athetosis (slow, writhing movements), abnormal eye movements, poor coordination, mood disturbance, dementia, dysphagia (difficulty swallowing).
Neurodevelopmental Conditions
- Neural Tube Defects (NTD): Spina bifida, loss of sensation/paralysis, bladder and bowel disturbance, seizures, leg and foot deformity.
- Chiari Malformation: Cerebellar and brainstem tissue slip into the foramen magnum. Symptoms: occipital headaches worse with Valsalva maneuvers, vomiting; cerebellar dysfunction (vertigo, dizziness, nystagmus, gait instability); posterior fossa symptoms (cough, gag reflex, breathing, sleep apnea problems).
Neuromuscular Disorders
- Symptoms: Muscle weakness, fatigue, disability, upper vs. lower motor neuron signs, ptosis (drooping eyelid), diplopia (double vision). Possible respiratory failure.
- Examples: Motor neuron disease, myasthenia gravis.
Pain
- Peripheral Neuropathy (PN): Burning pain, numbness/tingling, sensory loss, limb weakness.
- Trigeminal Neuralgia (TM): Paroxysmal (sudden, sharp) pain; dull pain between paroxysms; facial muscle spasms, autonomic symptoms (tearing, eye redness, runny nose).
Tumours
- Symptoms: Headaches, nausea, vomiting, raised intracranial pressure (brain herniation), seizures, muscle weakness, numbness, personality, visual, or speech changes. Tumors are space-occupying lesions.
- Examples: Benign (meningioma, neurofibroma); malignant (glioblastoma, astrocytoma).
Trauma
- Traumatic brain injury (TBI): Confusion, memory loss, headache, nausea, vomiting, loss of consciousness.
- Spinal cord injury (SCI): Paralysis.
- Hypoxic brain injury (e.g., cerebral palsy): Spasticity, hypertonia (increased muscle tone), involuntary movements.
Altered Level of Consciousness
- Symptoms: Seizures, muscle jerks, sensory changes, incontinence, confusion, memory loss, coma.
- Examples: Epilepsy, hypoglycemia, hypoxia, infection, overdose, medication/toxins.
