NEUROLOGY- 2 MARKS- PART 9

DERMATOMES:

  • A dermatome is the area of sensory nerves near the skin that are supplied by a specific spinal nerve root.
  • The body can be divided into regions that are mainly supplied by a single spinal nerve.
  • There are eight cervical (one for the head, and one for each cervical vertebra), twelve thoracic, five lumbar and five sacral spinal nerves. Dermatomes are useful for finding the site of damage to the spine. 

ATHETOSIS:

  • Involuntary writhing movements, particularly of the arms and hands. Athetosis is associated with several neurological disorders, such as cerebral palsy and Rett syndrome.


LONG TERM MEMORY:

  • Long-term memory refers to the storage of information over an extended period.
  • If you can remember something that happened more than just a few moments ago whether it occurred just hours ago or decades earlier, then it is a long-term memory.


BERG BALANCE SCALE:

  • Berg Balance Scale The Berg Balance Scale (BBS) was developed to measure balance among older people with impairment in balance function by assessing the performance of functional tasks.
  • It is a valid instrument used for evaluation of the effectiveness of interventions and for quantitative descriptions of function in clinical practice and research.

Equipment needed:

Ruler, two standard chairs (one with arm rests, one without), footstool or step, stopwatch or wristwatch, 15 ft walkway

Time: 15-20 minutes

Scoring: A five-point scale, ranging from 0-4. “0” indicates the lowest level of function and “4” the highest level of function. Total Score = 5

Interpretation: 41-56 = low fall risk 21-40 = medium fall risk 0 –20 = high fall risk


AMYOTROPHIC LATERAL SCELEROSIS:

  •  A classic motor neuron disease. Motor neuron diseases are progressive chronic diseases of the nerves that come from the spinal cord responsible for supplying electrical stimulation to the muscles.
  • The disease is therefore usually referred to simply as ALS.

    INTRACRANIAL PRESSURE:

    Increased intracranial pressure is a rise in the pressure inside the skull that can result from or cause brain injury.

    Many conditions can increase intracranial pressure. Common causes include:

    • Aneurysm rupture and subarachnoid hemorrhage
    • Brain tumor
    • Encephalitis irritation and swelling, or inflammation, of the brain)
    • Head injury
    • Hydrocephalus(increased fluid around the brain)
    • Hypertensive brain hemorrhage (bleeding in the brain from high blood pressure)
