Neurological Assessment Slides 1-20 Flashcards
Two regions of Nervous system
Central Nervous System (CNS)
Peripheral Nervous System (PNS)
CNS - Brain
Control center of body
Covered and protected by scalp, skull, and meninges
Blood brain barrier
Cerebrum - right and left hemispheres, frontal, parietal, occipital & temporal lobes
Diencephalon - (thalamus and hypothalamus) body temp, sleep
Cerebellum - position sense, posture & equilibrium/balance
Brain Stem - (medulla oblongata, pons & midbrain) resp. & cardiac regulation, sneezing
Lobes of the Cerebrum
Parietal – somatic sensory center
Frontal – higher intellect, speech production, personality, behavior, emotions, voluntary movement
Temporal – hearing, memory, speech perception and translation
Occipital – vision
CNS – Spinal Cord
- Extends from medulla to the level of the first lumbar vertebra
- Cord protected by vertebra, meninges and cerebral spinal fluid
- Gray matter is on the inside and white matter on the outside
- Mediates deep tendon reflexes
Spinal Roots
Cervical, thoracic, lumbar nerves
Posterior (sensory) roots
Anterior (motor) roots
Damage to posterior – loss of sensation
Damage to anterior – flaccid paralysis
Peripheral Nervous System (PNS)
The PNS links CNS with the rest of the body
External environmental information received and transmitted via PNS
- Cold, wet, hot, pain
Spinal Nerves
Cervical 8 pairs C1-C8
Thoracic 12 pairs T1-T12
Lumbar 5 pairs L1-L5
Sacral 5 pairs S1-S5
Coccygeal 1 pair Coccyx
Reflex
Rapid involuntary predictable motor response to a stimulus. Reflex arc, is not dependent on the brain.
Somatic
-Skeletal muscle contraction
Autonomic
-Cardiac, smooth muscle and glands
Three basic types of neurologic examination
Screening neurologic exam
Complete neurologic exam – neurologic concerns
Neurologic recheck exam
Assessment
Neurologic Exam
Assess mental status first
Equipment
Equipment
Eye charts, tuning fork, pen light, reflex hammer, key, buttons, coin, big safety pin
Mental Status
- Level of consciousness (LOC)/orientated, intact recent and remote memory
- Cognitive abilities and mentation
Level of consciousness (LOC)/orientated, intact recent and remote memory
Confusion/disorientation
Lethargy
Delirium
Coma
Glasgow Coma Scale – eye opening, verbal response, motor response
Cognitive abilities and mentation
Mini Mental State Examination
Mental Status Exam
The GlasgowComaScale (GCS) is a calculated scale that determines a patient’s level of consciousness. Medical professionals use it to evaluate patients with:
traumaticbrain injury
altered mental status
