1 The Many Faces of Cerebral Palsy Dr Emeka Ejeliogu Lecturer/Consultant Paediatric Neurologist University of Jos/Jos University Teaching Hospital

2 What is cerebral palsy Cerebral palsy (CP) is a chronic motor disorder involving posture and/or movement that results from a non-progressive injury to the developing brain. CP is not a progressive disorder but it usually evolves over time, however it may appear to be progressive especially to concerned and worried parents and other family members. CP is not curable because the brain neurones affected by the injury cannot be regenerated. However if a child with CP is identified early and early intervention instituted, the child could attain his/her full potential and function at a high educational and vocational level.

3 Prevalence in developed countries  Prevalence rate is 1-3 per 1000 children  In USA:  About 764,000 children and adults currently have cerebral palsy  About 500,000 children under age of 18 currently have cerebral palsy  About 2-3 children out of every 1,000 have cerebral palsy  About 10,000 babies born each year will develop cerebral palsy

4 Prevalence in developing countries No population based studies in Nigeria & most other developing countries Couper 2002 in Kwazulu, S.A reported a prevalence rate of 28 per 1000 children If we assume a prevalence rate of 28 per 1000 in Nigeria, and a population of 160m then as many as 2m children may be living with CP in Nigeria

5 Causes CP is caused by a broad group of problems that occur during: Pregnancy Labour and delivery After birth The problem could affect: The mother The foetus The child

6 During pregnancy MaternalFoetal Maternal infections Chorioamnionitis Antepartum haemorrhage Maternal drug abuse Trauma to the abdomen Abdominal irradiation Congenital malformations of the brain Other congenital anomalies esp cardiovascular Congenital infections Cord accidents

7 During labour & delivery maternalInfant Prolonged obstructed labour Precipitate labour Instrumental delivery Severe birth asphyxia Prematurity Multiple birth Intracranial haemorrhage Birth trauma Neonatal jaundice Hypoglycaemia Meningitis/Encephalitis

8 After birth Meningitis Encephalitis Head injury Thromboembolism Severe shock Sickle cell stoke

9 Causes... 2 In Nigeria the commonest causes are: – Severe birth asphyxia – Severe jaundice – Prematurity – Meningitis

10 Classifications CP may be classified in different ways. The most acceptable classifications are the International and the functional classifications which both classify CP into 4 International classification Spastic CP Athetoid CP Ataxic CP Mixed CP

11 Classification 2 Functional classification – Class I-no limitation of activity – Class II-slight to moderate limitation – Class III-moderate to great limitation – Class IV-no useful physical activity

12 Signs and Symptoms of Cerebral Palsy Muscle tone Movement coordination and control Reflexes Posture Balance Fine motor function Gross motor function Oral motor function

13 Muscle tone Hypotonia Hypertonia Dystonia Mixed Muscle spasms Fixed joints Abnormal neck or truncal tone Clonus

14 Movement coordination Spastic Athetoid or dyskinetic movements Ataxic movements Mixed movements Gait disturbances

15 Balance Requiring both hands for support Having difficulty balancing when not using hands for support Unable to sit without using hands for support Swaying when standing Unsteady when walking Difficulty making quick movement Walking with abnormal gait

16 Gross motor function Impaired gross motor functions – limited capability of accomplishing common physical skills such as crawling, walking, running, jumping, and maintaining balance. Delayed gross motor functions – physical skills developed later than expected.

17 Fine motor function Grasping small objects Holding objects between thumb and forefinger Setting objects down gently Using crayons Turning pages in a book

18 Oral motor function Speaking Swallowing Feeding/chewing Drooling

19 Associated Disabilities  CP may be associated with a spectrum of developmental disabilities, including  Intellectual disability  Seizure disorder  Visual defect  Hearing impairment  Speech defect  Cognitive dysfunction  Behavioural problems  ADHD

20 Early identification Appropriate follow-up of children with known risk factors like Neonatal jaundice, Severe Birth Asphyxia, Prematurity, and Meningitis. Newborn examination with emphasis on general activity (floppiness, hyperalert), poor feeding, and seizure. Physical examination with the following in mind: – Persistence of primitive reflexes – Movement of the limbs: limited movement of one side of the body/hand dominance before 1year Educating mothers on children’s developmental milestones and asking them to seek medical care whenever they notice any delay. Routine assessment of developmental milestones during immunization and well-infant clinic visits. Training of healthcare worker on early identification of signs and symptoms of CP

21 Goal of treatment  Optimize mobility  Manage primary conditions  Control pain  Prevent and manage complications, and associated conditions  Maximize independence  Enhance social and peer interactions  Foster self-care  Maximize communication  Maximize learning potential  Enhance quality-of-life

22 Treatment  A multidisciplinary team provide important contributions to the treatment of children with CP. These include:  Physicians from various specialties  Occupational and physical therapists  Speech therapists  Social workers/counsellors  Special educators  Developmental and clinical psychologists  Counselling is very important as soon as the diagnosis is made  Family support is crucial

23 Prognosis Long term outcome depends on the severity of the motor disability; and the presence & severity of cognitive dysfunction. Other factors that determine the prognosis include: – Other associated disabilities – Level of motivation of the family – Family, community & social support – Type & intensity of facilities available for rehabilitative intervention

24 Prevention Well supervised pregnancy and safe delivery Appropriate investigations during pregnancy Early identification of high risk pregnancies Well trained birth attendants Efficient resuscitation of asphyxiated babies Good referral system Newborn examination and screening Good newborn care including intensive care Prompt diagnosis and appropriate management of NNJ Prompt diagnosis and appropriate treatment of meningitis

25 Other diagnostic considerations Developmental delay Physical disability Behavioural problem Developmental disability Neurodegenerative problem

26 Developmental delay Constitutional delay in development – Social smile6-8 weeks – Neck control2-3 months – Sit without support4-6 months – Crawl7-9 months – Walk12-18 months

27 Physical disabilities Muscular dystrophies: Duchenne/Becker – Inherited as an X-linked recessive trait-boys usually affected – Absence of dystrophin, a cytoskeletal protein encoded on X chromosome – Hypertrophy of the calves – Progressive muscle weakness – Proliferation of connective tissue in muscle. – Intellectual impairment – Loss of ambulation by 7-10 years – Contractures and scoliosis are common

28 Behavioural problem Attention deficit hyperactivity disorder (ADHD) – Inattention and difficulty sustaining attention – increased distractibility – poor impulse control and decreased self-inhibitory capacity – motor overactivity – academic underachievement – Poor interpersonal relationships with family members and peers – Evidence suggest that genetic and environmental factors play significant role during foetal and postnatal development in the evolution of ADHD

29 Developmental disability Down syndrome Autism spectrum disorder – Autism – Asperger syndrome Intellectual disability

30 Down syndrome Presence of 3 chromosome 21 instead of 2 Occurs as a result of non-dysjunction in one parent Incidence increases with increasing maternal age Presents with – Hypotonia – Flat face, low-set ears – Upward and outward slanted palpebral fissures – Varying degrees of intellectual disability and growth retardation – Cardiac malformations – Single transverse palmer crease (simian crease)

31 Autism spectrum disorder (ASD) A neurodevelopmental disorder characterized by: Impaired social interaction. poor eye contact, little symbolic play, limited joint attention Impaired verbal and non-verbal communication reliance on non-verbal communication with delay in use of words echolalia Restricted, repetitive or stereotyped behavior. Stereotypical body movements a marked need for sameness a very narrow range of interests

32 Autism spectrum disorder... 2 The diagnostic criteria require that symptoms become apparent before a child is three years old. Cause is multifactorial- combination of genetic and environmental factors Indication to proceed with evaluation for ASD – No babbling by 12 months. – No gesturing (pointing, waving, etc.) by 12 months. – No single words by 16 months. – No two-word phrases by 24 months. – Any loss of any language or social skills, at any age. Autism is the most severe type Asperger syndrome is a milder type with relative preservation of language and intellectual function

33 Intellectual disability Intellectual capacity that is so impaired that there is need for special care or special education IQ test is used to determine if a child has intellectual disability Common causes of intellectual disability include – genetic syndromes – chromosomal abnormalities – foetal deprivation – prematurity – perinatal insults – intrauterine exposure to drugs of abuse

34 Intellectual disability... 2 Mild – can function as an independent adult if well adjusted, he can be educated but most will require special education. Moderate – is trainable, he can learn to read and write but needs close supervision. The well adjusted ones can function semi-independently in a sheltered workshop. Severe – may be able to protect himself against physical danger, however he is not trainable Profound – unable to protect himself against physical danger, cannot speak more than a few words, may require care similar to that needed for a baby

35 Neurodegenerative problems Inborn errors of metabolism Rett syndrome

36 Inborn errors of metabolism A large group of genetic diseases involving disorders of metabolism. The majority are due to defects of single genes that code for enzymes that facilitate conversion of various substances (substrates) into others (products). In most of the disorders, problems arise due to accumulation of substances which are toxic or interfere with normal function, or to the effects of reduced ability to synthesize essential compounds.

37 Inborn errors of metabolism Common ones: – Galactosaemia – Glycogen storage disease – Phenylketonuria Features – Developmental delay – Seizures – Muscle weakness – Hypertonia – Intellectual disability

38 Rett syndrome A rare genetic postnatal neurological disorder of the grey matter of the brain that almost exclusively affects females. Caused by mutations in the gene MECP2 located on the X chromosome.MECP2 Initial development is normal. Onset occurs between 6 and 18 months of age. A period of developmental stagnation is followed by developmental regression involving language and motor milestones.

39 Rett syndrome Features similar to CP – Hypotonia – Delayed or absent ability to walk – Gait/movement difficulties – Ataxia – Abnormally small head – Spasticity – Chorea – Dystonia

40 The way forward Get a diagnosis from appropriate professionals. Get informed (separate fact from fiction and myths). Get counselling. Identify local interventions. Get involved or start a support group. Determine severity, do needs assessment. Determine clear indications and goals of alternative therapies. Include parents in any intervention which they should be able to incorporate into their everyday lives.

41 Coping tips Love your child--Focus first on the fact that this is your child and second on their special need. Allow time for grief--It is a normal process, don’t bottle-up emotions. Play with your child by getting down to his level so that he can really interact with you. Get therapy -- speech, occupational, physical, and educational -- as soon as possible. When professionals work with your child, learn as much as you can from them and how you can implement some of the techniques they use to challenge your child.

42 Take care of yourselves The stress of balancing career and family -- and balancing the needs of a child with disabilities with the needs of other children -- can also take a toll. Maintain your friendships and social activities. Plan fun activities with the whole family. Schedule special “alone time” with your partner/spouse or a close friend. Hire a babysitter or respite caregiver to give yourself a break. Read uplifting books written by other caregivers of children with special needs. Focus on the present instead of fretting about the future.

43 Conclusion Cerebral palsy may have many faces and could be confused with different clinical conditions. For children with CP to achieve their maximum potential and have an independent good quality life, we need to have appropriate diagnosis, early identification, and early intervention. We all are stakeholders in their care and we have to be advocates for the needs of children with CP and their families.
