Neurology Flashcards
Neuro exam
Mental status Cranial nerves Deep Tendon Reflexes Tone Power Sensation Cerebellar Gait
Seizure investigations
EEG CT head CBC, lytes Medications- eg phenytoin levels LP (if new onset, fever, clinical signs)
Seizure history
- onset, chronology
- frequency- increasing, decreasing
- duration
- describe seizures: sequence of events, movements, salivation, tongue biting, incontinence, incontinence, aura (visual, smell)
- new symptoms: headache, vomiting, neuro deficits
- post itcal: headache, limb pain, todd’s paralysis
- medications: which ones, dose, how long, compliance
- Basic info: PMHx, PSHx, Meds, Allergies
Focused physical exam for a 60 year old female with acute confusion
vitals GCS Cranial nerve exam CNII- visual fields, fund CNIII- EOM CN II, III pupillary reflex, accommodation CN V facial sensation, clench teeth CN VII facial movements CN IX, X: gag, movement of palate CN VIII: hearing, CXI: sternocleidomastoid power, trapezius CXII: tongue
Power: arms, legs, hands Sensory: light touch, pin prick Reflexes Babinski Cerebellar: finger to nose, heel to shin Tone: cog wheeling Gait Balance (rhomberg)

Ddx neck pain and left arm weakness
- Musculoskeletal/muscular strain
- Disc degeneration, disk herniation
- Spondylosis (degenerative, osteoarthritis)
- cervical spondylytic myelopathy (degenerative changes narrowing the spinal canal)
- cervical radiculopathy (dysfunction of the spinal nerve root that may manifest with pain, weakness, reflex changes, or sensory changes)
- Malignancy
Red flags for neck pain/those who need imaging
History of recent significant fall or major trauma Unexplained weight loss Fever or chills History of cancer Immunosuppression Intravenous drug use Chronic steroid use Neurological signs or symptoms (arm clumsiness, gait difficulty, bowel or bladder dysfunction, Babinski's sign)
Neck Pain exam
Inspection: symmetry, erythema/bruising, atrophy (sternocleidomastoids), deformity,
Palpation: notes, masses, dorsal vertebral spines
Neck range of motion: flex, extension, rotation, lateral flexion
Shoulders/arms/hands
- inspection: symmetry, atrophy, deformity, skin lesions
- strength:
- Bicep flex: C5, C6
- Tricep ext: C6,7,8
- wrist extension: C6,7,8
- Grip: C7,8,T1
- Finger abduction: C8,T1, ulnar
- Opposition of thumb: C8,T1, median
- Sensation
- Deep tendon reflexes
Investigations
Indications for neck xray
- Age >50 years with new symptoms
- Constitutional symptoms (fevers, chills, unexplained weight loss)
- Moderate to severe neck pain lasting more than six weeks
- Progressive neurological findings
- Infectious risk (eg, injection drug use, immunosuppression)
- History of malignancy
Sensation of the hand
- median
- ulnar
- radial
Median: palmar surface of thumb, index, middle, thenar side of ring finger
Ulnar: 4th and 5th finger (dorsal and palmar)
Radial: dorsal surface of thumb, index, middle to PIP
Cervical radiculopathy management
- conservative therapy: soft collar, NSAIDS and acetaminophen
- if persistent symptoms then refer to neurosurgery, may ask for CT neck, may require surgery (decompressive laminectomy, anterior disectomy/graft fusion)
History for Carpel tunnel syndrome
age, occupation
-work done with hands
-onset, duration, chronology, time of day,
aggravating/relieving factors
-previous episodes, previous investigations
- associated symptoms: pain at night, diff opening jars, previous injuries
- functional limitations/work limitations
- neuro symptoms: pain, numbness, weakness in other areas, vision, headache, neck pain, nausea
Basic info: PMHx-diabetes, hypothyroid, rheumatoid artheritis, pregnancy, PSHx, meds, allergies,
Differential for carpal tunnel syndrome
carpal tunnel syndrome
cervical radiculopathy
brachial plexus injury
diabetic peripheral neuropathy
Investigations for carpal tunnel syndrome
Nerve conduction studies
Treatment for carpal tunnel syndrome
- wrist splint
- modified work
- local corticosteroid injection
- surgical decompression via flexor retinaculum release
