Examination of Central nervous system
This is one of the few feared areas in medicine. It is easier to remember if you make sure you write this below format repeatedly and use it every time you examine a patient
Below is a brief note of headings for easy revision in exams. For detailed examination, look into individual articles.
Look around the room to see if any accessories/ instruments like

- Position of limbs- flexed, contractures, atrophy
General examination
- Level of consciousness- Alert/ Oriented/ cooperative
- Gait and Decubitus (position in bed)
- Asymmetry in the body parts
- Any obvious dysmorphism
Head
Size of head
- Microcephaly
- Macrocephaly
Shape of head
- Plagiocephaly- commonly seen in preterm
- Brachycephaly- commonly seen in ‘Down’s syndrome’ and ‘Crouzon syndrome’
- Scaphocephaly- can be seen in ‘Craniosynostosis’
Face
- Dysmorphism- Head sizeports, stoma, nasogastric tube, tracheostomy
- Neck lines, scars over the head
Neck
- Webbing

- Drooping eyelids
Ears
- Hearing aids
- Ear tags
- Low lying ears
Mouth
- Dentition
- Tongue- fasciculation,deviation , macroglossia
- Speech, stuttering,articulation
- Drooling

- Vagus- hoarseness of voice
- Accessory- shrugging of shoulders
- Hypoglossal- Deviation of tongue
- Motor system
- Power or weakness in muscles
- Wasting of muscles
- Fasciculation
- Involuntary movements
- Pain in muscles
- Gait abnormalities
- Sensory system
