Study Notes

Neurological Examination

The examination assesses sensory neuron and motor responses, including reflexes, to localize lesions and determine nervous system impairment.

Mental Status Examination

The purpose is to obtain evidence of symptoms and signs of mental disorders, including danger to self or others.
Components:
- Alertness: level of verbal or motor response to a specific stimulus.
- Cognition:
  - Orientation: time and place awareness.
  - Memory: recalling three objects.
  - Intellect: simple calculations or fact recall.
  - Abstraction: interpreting a proverb or comparing apples and oranges.
  - Judgment: responding to an ambiguous situation.
- Mood and Affect:
  - How the patient feels.
  - How the patient comes across to others.
- Thought Content:
  - Abnormal thought content includes hallucinations, paranoid behavior, and loss of reality.
  - Associated with delirium and schizophrenia.

Focal Cortical Functioning

Aphasia: defect in language processing, including speaking, reading, and writing.
Apraxia: defect in performing complex motor tasks, such as dressing.
Agnosia: difficulty interpreting sensory data from the environment or one's own body.
Subtypes of agnosia:
- Inattention/hemiagnosia: deficit in attention to and awareness of the contralateral side of the body or environment.
- Astereognosis: difficulty perceiving objects through tactile stimulation.

Skull, Spine, and Meninges

The central nervous system (CNS) consists of the brain and spinal cord, protected by the skull, spine, and meninges.
Lesions affecting these structures are commonly associated with neurological signs and symptoms.
Examination steps:
- Palpate the skull to detect trauma or surgery.
- Inspect for hematomas, particularly below the eyes and behind the ears.
- Inspect the spine for scoliosis.
- Check tenderness and range of motion in the cervical and lumbar regions.
- Examine for severe neck pain made profoundly worse with neck flexion (meningismus).
Tests for injuries to the skull, spine, and meninges:
- Straight leg raise test (sciatic stretch test).
- Brudzinski sign: spontaneous flexion of the legs at the hips and knees following neck flexion.
- Kernig sign: resistance to knee extension when the hips are flexed, indicating meningeal inflammation.
