Neurological Assessment Health Assessment
Objectives • Describe the anatomy and physiology of the nervous system. • Develop questions to be used when completing the focused interview. • Describe the techniques required for assessment of the nervous system. • Differentiate normal from abnormal findings in physical assessment of the neurologic system.
Neurologic System Complex Integration, Coordination, and Regulation of Body Systems
Nervous System • Central • Peripheral
Central Nervous System • Brain • Spinal cord
Brain • Cerebral cortex • Frontal • Parietal • Occipital • Temporal • Diencephalon • Thalamus • Hypothalamus • Epithalamus
Brain • Cerebellum • Brain stem • Midbrain • Pons • Medulla oblongata
Spinal Cord • Meninges • Cerebrospinal fluid • Vertebrae
Peripheral Nervous System • Cranial nerves • Spinal nerves
12 Pairs of Cranial Nerves • Originate in the brain • Control many activities in the body • Take impulses to and from the brain
Cranial nerves and their target regions. (Sensory nerves are shown in blue; motor nerves, in red.)
Spinal Cord • 31 pairs of spinal nerves • 8 pairs of cervical nerves • 12 pairs of thoracic nerves • 5 pairs of lumbar nerves • 5 pairs of sacral nerves • 1 pair of coccygeal nerves • Dermatome
Focused Interview • Specific questions • Illness, infection, or injury • Symptoms • Pain • Behaviors
Physical Assessment of the Neurologic System • Techniques • Inspection • Palpation • Auscultation of the carotid arteries • Sensory and motor function • Reflexes
Areas of the Neurologic System Assessment • Observing mental status, speech, and language • Observing sensorium, memory, calculation ability, abstract thinking ability, mood, emotional state, perceptions, thought processes, ability to make judgments
Cranial Nerves l. Olfactory: smell ll. Optic: vision lll. Oculomotor: moves eye constricts pupil, opens eyelid lV. Trochlear: moves eye in and down
Cranial Nerves V. Trigeminal: sensation to face, scalp cornea Vl. Abducens: moves eye laterally Vll. Facial: moves face Vlll. Acoustic: hearing and balance
Cranial Nerves lX. Glossopharyngeal: swallow & speech X. Vagus: voice quality Xl. Spinal Accessory: moves head & shoulders Xll. Hypoglossal: moves tongue
Cranial Nerves Assess together: lll, lV & Vl (EOMs) Assess together: lX, X & Xll (swallow, gag & dysarthria)
Areas of the Neurologic System Assessment • Motor function • Observation of gait and balance • Administration of the Romberg test • Administration of the finger-to-nose test • Observation of rapid alternating action movements • Administration of the heel-to-shin test
Areas of the Neurologic System Assessment • Sensory function • Observation of light touch identification • Sharp, dull, temperature, and vibration determination • Stereognosis • Graphesthesia • Two-point discrimination • Topognosis • Position sense
Areas of the Neurologic System Assessment • Reflexes • Biceps • Triceps • Brachioradialsis • Patellar • Achilles • Plantar • Abdominal
