2. Long term effects of chronic neurological conditions Flashcards
Epidemiology of chronic neuro condiitions
- 10 million in UK living with neurological condition impacting on their lives
- 1 million (2%) in UK disabled by their neurological condition
- 600,000 (1%) newly diagnosed each year with neurological condition
What is spina bifida?
a group of congenital conditions where there is an incomplete development or covering of the brain and/or spinal cord, caused by a failure of the foetal spine to close normally in the first month of pregnancy
Potential cause of spina bifida?
Folic acidic deficiency
What is cerebral palsy?
Spectrum of motor disorders affecting posture, movement and co-ordination
Cause of cerebral palsy>?
Brain lesion resulting in abnormal development of CNS
Incidence and prevalence of CP?
2-3 per 1000 live births in the UK
Prevalence in scotland is 15,000 cases
Spinal cord closure in…
first 30 days
Anterior neuropore at closure at….
26 days
Posterior neuropore closure at…..
29 days
Difference between mild and severe disability in spina bifida?
Mild: When cord remains in neural canal
- Sac contains the meninges and CSF but not the spinal cord
- Mild disability
- Least common
Serious: Cord is displaced from the neural canal or has not been developed
Neurological consequences of severe spina bifida
Lower motor neurone lesion
Paralysis, loss of sensation and reflexes distal to the abnormality
Neonatal consequences of severe spina bifida
High risk of meningitis in open lesions in the neonate
Hydrocephalus in 70-90% because of the interruption of the circulation of CSF
Shunting of hydrocephalus, problems?
Shunts can become infected or blocked.
Shunts used to relieve high ICP
Hydrocephalus, associated conditions?
Renal anomalies
Sphincter function
Intellectual impairments Musculoskeletal
Neural abnormalities, antenatal diagnosis techniques?
• Ultrasound
spinal anomalies identifiable at 16-18 weeks
• α fetoprotein raised in neural tube defects maternal serum at 16-20 weeks amniocentesis
