1. Course Topic Overview: Neurological Disorders
Definitions
Primary care neurological evaluation encompasses the assessment, diagnosis, evidence-based
pharmacotherapy, and chronic management of disorders affecting the central neurological
system (brain, spinal cord) and peripheral nervous system (cranial nerves, peripheral nerves,
neuromuscular junction). Key categories include primary headache syndromes, cerebrovascular
disease, neurodegenerative conditions, demyelinating diseases, seizure disorders, movement
disorders, peripheral neuropathies, and neuromuscular transmission defects.
Pathophysiology
● Cerebrovascular Disease (TIA/Stroke): Ischemic disruption of cerebral blood flow
leading to focal hypoxia, ATP depletion, cytotoxic edema, and neuronal cell death; or
intracranial vascular rupture (hemorrhagic) causing localized hematoma and elevated
intracranial pressure (ICP).
● Neurodegenerative Disorders:
○ Alzheimer’s Disease: Extracellular beta-amyloid plaque aggregation and
intracellular hyperphosphorylated tau neurofibrillary tangles causing progressive
cortical and hippocampal atrophy.
, ○ Parkinson’s Disease: Progressive degeneration of dopaminergic neurons within
the substantia nigra pars compacta, leading to dopamine depletion and
intracellular Lewy body (alpha-synuclein) inclusion formation.
○ Dementias (DLB/FTD/Vascular): Alpha-synuclein accumulation in Lewy body
dementia; focal frontotemporal lobar degeneration; or cumulative microvascular
ischemic white matter injury in vascular dementia.
● Demyelinating Disorders (Multiple Sclerosis): Autoimmune T-cell and B-cell mediated
inflammation targeting myelin basic protein, causing demyelination, axonal transection,
and reactive gliosis (plaques) within the central nervous system.
● Seizure Disorders: Imbalance between neuronal excitation (glutamate/NMDA) and
inhibition (GABA), leading to paroxysmal, hypersynchronized electrical discharge within
cortical networks.
● Primary Headache Syndromes:
○ Migraine: Trigeminovascular system activation triggering neurogenic
inflammation, calcitonin gene-related peptide (CGRP) release, and cortical
spreading depression.
○ Cluster Headache: Trigeminal-autonomic reflex activation with hypothalamic
pacemaking dysregulation.
○ Temporal (Giant Cell) Arteritis: Granulomatous pan-arteritis targeting medium
and large cranial arteries (branches of external carotid).
● Peripheral & Neuromuscular Disorders:
○ Bell’s Palsy: Acute inflammatory swelling or reactivation of HSV-1 within the facial
nerve (CN VII) canal leading to peripheral nerve compression.
○ Myasthenia Gravis: Autoimmune T-cell mediated IgG autoantibodies targeting
postsynaptic nicotinic acetylcholine receptors (AChR) or muscle-specific kinase
(MuSK) at the neuromuscular junction.
○ Trigeminal Neuralgia: Vascular compression (often superior cerebellar artery) of
the trigeminal nerve (CN V) root entry zone causing focal demyelination and
ephaptic transmission.
Risk Factors
● Vascular: Hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation, smoking,
carotid stenosis, obesity, advanced age.
● Autoimmune/Genetic: HLA-DRB1 allele (MS), positive family history of migraine or
early-onset dementia, ApoE4 gene carrier state (Alzheimer's).
● Environmental/Iatrogenic: Vitamin B12 deficiency, alcohol overuse, neurotoxic
chemotherapeutic exposure, head trauma, environmental toxins (pesticide exposure in
Parkinson’s).
Clinical Manifestations
● Focal Neurological Deficits: Sudden hemiparesis, facial droop, aphasia, dysarthria,
hemispatial neglect, visual field cuts (homonymous hemianopia).
, ● Cognitive/Behavioral: Memory impairment, executive dysfunction, apraxia, agnosia,
visual hallucinations, personality change, depression, daytime fatigue.
● Motor & Movement: Resting tremor, cogwheel rigidity, bradykinesia, postural instability,
spasticity, fasciculations, ascending symmetrical weakness.
● Sensory & Cranial Nerves: Stocking-glove paresthesias, electric-shock facial pain,
diplopia, ptosis, dysphagia, optic neuritis (monocular vision loss with painful eye
movement).
Assessment Findings
● Physical & Neurological Exam:
○ Cranial Nerves: CN II–XII evaluation; test CN VII (forehead involvement
distinguishes peripheral Bell's palsy from central upper motor neuron stroke).
○ Motor & Reflexes: Upper motor neuron (UMN) signs (hyperreflexia, clonus,
extensor Babinski response) vs. Lower motor neuron (LMN) signs (hyporeflexia,
flaccidity, fasciculations, muscle atrophy).
○ Cerebellar: Heel-to-shin, rapid alternating movements, finger-to-nose, dysmetria,
dysdiadochokinesia, tandem gait.
○ Meningeal Signs: Kernig sign (knee extension produces back/thigh pain) and
Brudzinski sign (passive neck flexion induces involuntary hip/knee flexion).
○ Cognitive Screening: Mini-Mental State Examination (MMSE) or Montreal
Cognitive Assessment (MoCA; score $<26/30$ indicates cognitive impairment).
Differential Diagnoses
● TIA vs. Acute Ischemic Stroke vs. Focal Seizure with Todd's Paresis vs. Complicated
Migraine
● Alzheimer's Disease vs. Vascular Dementia vs. Normal Pressure Hydrocephalus vs.
Pseudodementia (Major Depression)
● Essential Tremor vs. Parkinsonian Rest Tremor vs. Drug-Induced Extrapyramidal
Symptoms
● Bell's Palsy vs. Acute Stroke involving CN VII fibers
● Multiple Sclerosis vs. Neuromyelitis Optica vs. Vitamin B12 Deficiency Subacute
Combined Degeneration
Diagnostic Testing
● Neuroimaging:
○ Non-contrast Brain CT: Mandatory initial test to exclude intracranial hemorrhage
prior to thrombolysis in acute stroke.
○ Brain/Spine MRI with/without Contrast: Gold standard for detecting demyelinating
MS plaques (periventricular Dawson fingers, gadolinium-enhancing lesions),
ischemic stroke, tumors, and structural lesions.
