Cerebral Palsy
This is not one condition but is a group of disorders
which generally involve either impairment of movement or loss of other nerve
functions causing physical and/or mental disability. These disorders are
caused by injury to the brain, usually during fetal development and may be
due to clinical negligence occurring during labour and delivery.
Classically a person with cerebral palsy (“CP”) has
decreased muscle tone known as spasticity and in addition, there may be
partial or full loss of movement, sensory abnormalities, and defects of
hearing and vision. Intellectual function may range from normal to severe
mental retardation.
Symptoms of CP are usually evident before the age of three
years and in severe cases may appear in the first three months after birth.
As the disorders are due to brain damage they are not-progressive ie. the
damage to the brain has already occurred and therefore the condition does not
get worse as the patient gets older (unlike, for instance, Alzheimer’s
disease or Parkinson’s disease). However, often the full extent of the
symptoms will not become apparent until the child starts developing and
increasingly complex milestones need to be reached.
Typical instances when CP has been held to result from
clinical negligence during delivery include:
·
lack of oxygen to the brain due to extended period in the birth
canal
·
failure to recognise and treat seizures in the new born child
·
inappropriate vacuum extraction or inappropriate use of
delivery forceps
·
delay in performing a caesarean section
·
foetal heart rate changes ignored
·
inadequate planning for potential large birth weight
·
inadequate consideration of maternal high blood pressure or
toxaemia
·
failure to recognise jaundice or meningitis or certain other
dangerous infections
·
prolapsed umbilical cord causing oxygen deprivation to the
brain
There are three main types of CP which may also be present
in a mixed form:
·
Spastic CP is the most common form, affecting about 80% of
sufferers. Patients have
stiff and jerky movements as a result of the
muscles remaining in a constant state of
increased involuntary reflex
·
Athetoid CP affects less than 20% of patients and produces
uncoordinated, involuntary,
purposeless movements, especially in the face,
arms, and trunk.
·
Ataxic CP affects less than 10% of patients and is
characterised by poor muscle tone
and
altered sense of balance and depth perception, leading to
slow, uncoordinated,
unsteady
and shaky movement.
