DEFINE HYDROCEPHALUS?

  • IT IS AN ACCUMULATION OF CEREBRO SPINAL FLUID (CSF) WITHIN THE BRAIN.
  • THIS TYPICALLY CAUSES INCREASED PRESSURE ISIDE THE SKULL.
  • IN BABIES THERE MAY BE A RAPID INCREASE IN HEAD SIZE.
  • OLDER PEOPLE MAY HAVE HEADACHE, DOUBLE VISION, POOR BALANCE, URINARY INCONTINENCE, PERSONALITY CHANGES, OR MENTAL IMPAIRMENT.

TYPES OF HYDROCEPHALUS?

  • COMMUNICATING
  • NON- COMMUNICATING.

SYMPTOMS OF HYDROCEPHALUS?

  • HEAD ACHE
  • VOMITING
  • NAUSEA
  • PAPILLEDEMA
  • SLEEPINESS
  • COMA
  • DOUBLE VISION
  • POOR BALANCE
  • URINARY INCONTINENCE
  • PERSONALITY CHANGES
  • MENTAL IMPAIRMENT.

DEFINE COMMUNICATING HYDROCEPHALUS?

  • COMMUNICATING HYDROCEPHALUS ALSO KNOWN AS NON- OBSTRUCTIVE HYDROCEPHALUS.
  • IT IS CAUSED BY IMPAIRED CEREBROSPINAL FLUID RE ABSORPTION IN THE ABSENCE OF ANY CSF – FLOW OBSTRUCTION BETWEEN THE VENTRICLES.

DEFINE NON- COMMUNICATING HYDROCEPHALUS?

  • NON COMMUNICATING HYDROCEPHALUS ALSO KNOWN AS OBSTRUCTIVE HYDROCEPHALUS.
  • IT IS CAUSED BY A CSF – FLOW ABSTRUCTION.

WRITE THE CHARACTERISTICS OF HYDROCEPHALUS?

  • VENTRICULAR ENLARGEMENT DISPROPORTIONATE TO THE DEGREE OF SULCAL WIDENING.
  • ENLARGEMENT OF TEMPORAL HORNE
  • PERIVENTRICULAR FLUID SECONDARY TO TRANSEPENDYMAL CSF PERMEATION.
  • IN CHILDREN <2 YEARS THE HEAD CIRCUMFERENCE IS OFTEN THE BEST DISTINGUISHING FEATURE BETWEEN HYDROCEPHALUS AND ATROPHY.

CAUSES OF HYDROCEPHALUS?

  • NEURAL TUBE DEFECTS
  • MENINGITIS
  • BRAIN TUMORS
  • TRAUMATIC BRAIN INJURY
  • INTRA-VENTRICULAR HEMORRHAGE
  • AQUEDUCTAL STENOSIS
  • SUB-ARACHNOID HEMORRHAGE.

RISK FACTORS OF HYDROCEPHALUS?

  • BRAIN SURGERY
  • HEAD INJURIES
  • BLEEDING FROM BLOOD VESSELS.

WHICH ARE SYMPTOMS OCCUR IN OLDER CHILDREN?

  • BRIEF, SHRILL, HIGH PITCHED CRY
  • CHANGES IN PERSONALITY , MEMORY.
  • CHANGES IN FACIAL APPEEARENCE AND EYE SPACING.
  • CROSSED EYES OR UNCONTROLLED EYE MOVEMENTS.
  • DIFFICULTY FEEDING.
  • EXCESSIVE SLEEPINESS
  • IRRITABILITY
  • POOR TEMPER COTROL
  • LOSS OF BLADDER CONTROL
  • LOSS OF CO-ORDINATION AND TROUBLE WALKING.
  • MUSCLE SPASTICITY.
  • SLOW GROWTH (CHILD 0-5 YEARS)
  • RESTRICTED MOVEMENTS
  • VOMITING

DEFINE AQUEDUCTAL STENOSIS?

  • THE NARROW PASSAGE BETWEEN THE THIRD AND FOURTH VENTRICLE IN THE BRAIN IS BLOCKED OR TOO NARROW TO ALLOW SUFFICIENT CEREBRAL SPINAL FLUID TO DRAIN.
  • FLUID ACCUMULATES IN THE UPPER VENTRICLES, CAUSING HYDROCEPHALUS.

COMPLICATIONS OF HYDROCEPHALUS?

  • WHEN THE CSF DRAINS MORE RAPIDLY THAN IT IS PRODUCED BY THE CHOROID PLEXUS.
  • IT CAUSES THE SYMPTOMS
  • LISTLESSNESS
  • SEVERE HEAD ACHE
  • HYPERESTHESIA
  • DIZZINESS
  • VERTIGO
  • MIGRAINES
  • SEIZURES
  • WEAKNESS IN ARMS AND LEGS
  • STRABISMUS
  • DOUBLE VISION.

MANAGEMENT OF HYDROCEPHALUS?

  • RELIEF OF THE HYDROCEPHALUS
  • TREATMENT OF COMPLICATIONS.
  • MANAGEMENT OF THE PROBLEM RELATED TO THE EFFECTS OF THE DISORDER ON PSYCHOMOTOR DEVELOPMENT.

SHUNTS OF HYDROCEPHALUS?

  • VENTRICULO – PERITONAL SHUNT
  • VENTRICULO – ATRIAL SHUNT
  • VENTRICULO – PLEURAL SHUNT
  • VENTRICULO – GALBLADDER SHUNT.

DIAGNOSIS OF HYDROCEPHALUS?

  • CT SCAN
  • MAGNETIC RESONANCE IMAGING (MRI).

MEDICAL MANAGEMENT OF HYDROCEPHALUS?

  • ACETOZOLAMIDE:-
  • DOSE OF 50MG/KG/DAY
  • IT DIMINSHES CSF PRODUCTION
  • ORAL GLYCEROL HAS ALSO USED FOR SIMILAR PURPOSE.
  • DIURETIC:-
  • INCREASES URINE PRODUCTION TO GET RI OF EXCESS SALT AND WATER.

DEFINE VENTRICULO – PERITONIAL SHUNT?

  • A TUBE INSERTED THROUGH A SMALL HOLE IN THE SKULL TO DRAIN EXCESS FLUID AND RELIEVE PRESSURE ON THE BRAIN.

SURGERY FOR HYDROCEPHALUS?

  • VENTRICULOSTOMY:-
  • SURGERY TO CREATE AN OPEING IN THE SKULL.
  • SO THAT AN INSERTED TUBE CAN DRAIN EXCESS FLUID FROM BRAIN.
  • IT IS OTHERWISE CALLED AS EXTERNAL VENTRICULAR DRAIN (EVD)

Hi. My name’s Cathy.And I’m glad to see you here. Here’s what you really need to know about me:I am a big fan of Body and Health. I love to learn about it. I love to grow in it. And I love to help others develop as Healthy Human.. And… I’m not a fan of technology. So a Web-Site might seem like an odd fit for me. So why am I here online? Because you are. For many years I’ve been able to help People through Consultation at Clinic, Conference at public, as a trainer Fitness Centre , and as articles in books. But in this 21st Century, more and more people are searching for resources on the Internet. So it’s time for me to bring my material to the world of computers. I hope to provide you with Physical Fitness teaching that is both timeless and timely. I’ll let you in on my book writing process. I’ll tell you what I’m reading. And occasionally, I’ll tell you what I think about what’s currently happening in the world of Physical Fitness and Health Conciousness — around the world. My hope is that what you find here will add value to your life and give you the tools to achieve your goals as a Healthy Human Being.
