Neurological Assessment Flashcards
Nervous System
Divided into two regions
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
CNS - BRAIN PARTS:
Cerebrum
Diencephalon
Cerebellum
Brain Stem
right and left hemispheres, frontal, parietal, occipital & temporal lobes
Cerebrum
(thalamus and hypothalamus) body temp, sleep
Diencephalon
position sense, posture & equilibrium/balance
Cerebellum
(medulla oblongata, pons & midbrain) resp. & cardiac regulation, sneezing
Brain Stem
Lobes of the Cerebrum
Frontal
Parietal
Temporal
Occipital
somatic sensory center
Frontal
higher intellect, speech production, personality, behavior, emotions, voluntary movement
Parietal
hearing, memory, speech perception and translation
Temporal
vision
Occipital
CNS – Spinal Cord: ECGM
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

-The PNS links CNS with the rest of the body
-External environmental information received and transmitted via PNS
-Cold, wet, hot, pain

Reflex
- Rapid involuntary predictable motor response to a stimulus. Reflex arc, is not dependent on the brain.

Confused Conversation
Inappropriate words
Incomprehensible sound
None
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
The scale measures three categories:
Eye opening (E)
Motor response (M)
Verbal response (V)
The GCS score is the sum of the score in each of the three categories, with a maximum score of 15 (normal) and a minimum score of 3 (deep unconsciousness), as follows:
GCS score = E + M + V
Score 13-15:
Mild Head Injury
Score 9-12:
Moderate Head Injury
Score of 8 or less:
Severe Head injury
Mental Status: LCPBA
- Level of consciousness orientated, intact recent and remote memory
-Cognitive abilities and mentation - Physical appearance, dress, grooming hygiene
- behavior affect and facial expression
-assess thought context/process
Speech and Language: QRVF
Quality
rate
Volume
Fluency
Fluency – Abnormal patterns
Aphonia/dysphonia
Cerebellar dysarthria
difficulty/discomfort in talking (laryngeal disease)
aphonia/dysphonia
distorted speech sounds, may sound unintelligible, basic language intact
cerebellar dysarthria
isa language disorder that makes it hard for you to read, write, and say what you mean to say. Sometimes it makes it hard to understand what other people are saying, too. Aphasia is not a disease. It’s a symptom of damage to the parts of the brain that control language.
Aphasia
Speech Abnormalities: Aphasia
Broca’s
Global
Wernicke’s
Thought Processes and Perception: PAI
Perceptions
Ability to make a decision/judgment
Insight
Cognitive Abilities and Mentation: IRRAI
immediate memory

Opisthotonos
Motor System (Cerebellum): CG
Coordination
Gait and Balance
is a term fora group of disorders that affect coordination, balance and speech. Any part of the body can be affected, but people with ataxia often have difficulties with: balance, walking, speaking.
Ataxia
Gait Abnormalities: SCPSSW
Spastic hemiparesis
cerebellar ataxia
Parkinsonian
Scissor
Steppage/footdrop
Waddling
Motor System: MT
Muscle size, strength, tone bilaterally
Tremor differentiation
Tremor Type: RAPIKI

Intention
Sensory Assessment: EPC
Exteroceptive sensation
Proprioceptive sensation
Cortical sensation
(also termed superficial sensation): receptors in skin and mucous membranes
Exteroceptive sensation
(also termed deep sensation): receptors located in muscles, tendons, ligaments and joints
Proprioceptive sensation
interpretative sensory functions that require analysis of individual sensory modalities by the parietal lobes to provide discrimination. Individual sensory modalities must be intact to measure cortical sensation.
Cortical sensation
Client sitting
Eyes closed
“Say where you are touched.”
Compare bilaterally, and distally to proximally.
Light Touch
Close eyes
Strike fork & start on most distal bony prominence & work medially with neuropathy
Ask when do you feel the vibration start and when do you feel the vibration stop.
Vibratory Sensation
Close eyes
Place object in hand
“Identify object.”
Test bilaterally with different objects.
Note speed and accuracy
Stereognosis
unable to identify object
Astereognosis
Close eyes
Draw letter or number on hand
“Identify figure.”
Test bilaterally
Note speed and accuracy
Graphesthesia (Parietal Lobe)
inability to identify figure
Agraphesthesia
continued movement after stimulations removed
Clonus
Meningeal Irritation: NKB
Nuchal rigidity
Kernig’s sign
Brudzinski’s sign
Assess for increased intracranial pressure (ICP): LMPV
Level of consciousness (LOC)
Motor function
Pupillary response
Vital signs
Newborn reflexes: RSPMTB
Rooting
Sucking
Palmar grasp
Moro
tonic neck
Babinski
this reflexstarts when the corner of the baby’s mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking.
Rooting
When something touches a baby’s palate, he or she starts to suck it.
sucking
stroking the palm of a baby’s hand causes the baby to close his or her fingers in agrasp
Palmar Grasp
it is a normal reflex for an infant when he or she is startled or feels like they are falling. The infant will have a startled look and the arms will fling out sideways with the palms up and the thumbs flexed
Moro
hen a baby’s head is turned to one side, the arm on that side stretches out and the opposite arm bends up at the elbow.
Tonic Neck-
occurs after the sole of the foot has been firmly stroked. The big toe then moves upward or toward the top surface of the foot.
