Cerebral Palsy: A Brief Review

Abstract

Cerebral palsy (CP) is a group of permanent movement disorders that appear in early childhood. Cerebral palsy is caused by abnormal development or damage to the parts of the brain that control movement, balance and posture. Risk factors include preterm birth, being a twin, certain infections during pregnancy such as toxoplasmosis or rubella, exposure to methylmercury during pregnancy, a difficult delivery and head trauma during the first few years of life, among others. About 2% of cases are believed to be due to an inherited genetic cause. A number of sub-types are classified based on the specific problems present.The treatment must be goal oriented, such as to assist with mobility, reduce or prevent contractures, improve positioning and hygiene, and provide comfort. Each member of the child’s multidisciplinary team, including the child and both parents, should participate in the serial evaluations and treatment planning.

involving posture and tone, occurring early in life not the result of
progressive neurological disease associated with visual, hearing,
dental, behavioural with or without seizures. Cerebral palsy is the
most common motor disability in childhood.
Incidence of Cerebral palsy in multiple births is 7.5/1000
live births and in Singletons it is 2.1/1000 live births and, more
in 1500grams or less is 80/1000. 10% of the global population
has some form of disability due to different causes, In India, it
is 3.8% of the population. Nearly 15-20% of the total physically
handicapped children suffer from Cerebral palsy. In India, the
estimated incidence is around 3/1000 live births. In an analysis of
1000 cases of CP it was found that spastic quadriplegia constituted
61% of cases followed by diplegia 22% [1]. The prevalence of CP
has increased somewhat as a result of the enhanced survival of
very premature infants weighing less than 1000 grams who go on
to develop CP at a rate of 15 per 100. Risk factors include preterm
birth, being a twin, certain infections during pregnancy such as
toxoplasmosis or rubella, exposure to methylmercury during

Early Diagnosis
Early signs of cerebral palsy include Cerebral palsy is a
clinical diagnosis made by an awareness of risk factors, regular
developmental screening of all high risk babies and neurological
examination. As in all medical conditions, a systematic approach
focusing on maternal, obstetric and perinatal histories, review
of developmental milestones, and a thorough neurological
examination and observation of the child in various positions
such as supine, prone, sitting, standing, walking and running is
mandatory. It is not possible to diagnose CP in infants less than

cognitive functioning. Orthopedic evaluation is a must as muscle
imbalance and spasticity cause subluxation/dislocation of the
hips, equinus deformities, contractures and scoliosis. An EEG is
obtained if there is history of epilepsy. Neuroimaging studies are
carried out if they have not been done in the neonatal period that
provided the etiology of CP. MRI studies is preferred to CT scans.
Genetic and metabolic tests are carried out if there is evidence
of deterioration or metabolic compensation, family history of
childhood neurological disorder associated with CP. Tests to rule
out coagulopathy in children with stroke is necessary [6]. Common
management Problems in Cerebral Palsy are feeding problems
failure to suck, tongue trusting, gagging and choking, vomiting and
regurgitation, dribbling, constipation, crying, screaming and sleep
disturbances, chilblains and cold injury and growth.
Treatment
Treatment of Cerebral Palsy is done by a team of Physicians
including neuro developmental paediatrician, paediatric
neurologist, physical medicine and rehabilitation specialists as
well as occupational and physical therapist speech pathologist,
social workers, educators and developmental psychologist,
physiotherapist and occupational therapist, is important to reduce
abnormalities of movement and tone and to optimise normal

work with their child in daily activities such as feeding, carrying,
dressing, bathing and playing in ways that limit the effects of
abnormal muscle tones. Physiotherapy by Bobath method, Peto,
Doman-Delacato methods. Surgeries for e.g. neurosurgery for
Spasticity, movement disorder (dystonia) etc. Orthopedic surgery
for contracture and dislocation. The Neurosurgical procedures
SPR (Selective Posterior Rhizotomy), SMF (Selective Motor
Fasciculotomy), Orthopedic procedures, STR (Soft Tissue Release)
surgeries and Tendon transfer are to be considered. Management
of Spasticity in Cerebral Palsy is by oral medications Baclofen,
Diazepam, Tizanidine, Dantrolene, Intrathecal Baclofenby
insertion of a drug delivery system for continuous infusion and
use of Botulinum Toxin. Small doses of levodopa and Artane
(trihexiphenidyl) is sometimes useful for treating dystonia.
Reserpine or tetrabenazine can be useful for hyperkinetic
movement disorders. Treatment of seizures according to the type
is essential, Brain tonics for few months to few years following
insult to brain are used. Spinal cord stimulation is another option
of treatment. In hemidystonic cases and in a few diffuse cases
stereo tactic thalamic-basal ganglionic stimulatory or ablative
surgery can be considered. The nano technology in future is likely
to be quite promising in this group of patients. Both physical and
mental exercises (Physiotherapy, occupational therapy, cognitive
therapy, special education) are essential during most of the period.
Neurostimulation method of the therapy, indeed, stimulates brain
and improves neuronal functions of the existing brain cells. Brain
has tremendous potential power which can be brought to light by
stimulating therapies .Cooling term infants with hypoxic ischemic
encephalopathy to 33.3 °C for three days, starting with in six
hours of birth, in perinatal asphyxia affected new borns reduces
the risk of dyskinetic or spastic quadriplegia. Following asphyxia
starting very early treatment will give the best results is to be
stressed. Assistive technology by equipment or devices to improve
independence e.g. walking frames, wheelchairs, adapted computer
access is being used. Communication skills may be enhanced by
the use of Bliss symbols, talking typewriters, electronic speech
