Q

What are the different types of generalised seizure?

A
  • Tonic-clonic seizure: bilateral increased tone and then bilateral sustained rhythmic jerking
  • Tonic seizure: Increased tone, most commonly happen while sleeping
  • Atonic seizure: sudden loss of muscle strength
  • Myoclonic seizure: shock-like jerks of muscles
  • Epileptic spasms: type of seizure seen in infancy

3-13yrs age at onset, peak 9yrs
Daytime and night time seizures

Q

What is sudden death in epilepsy?

A

When no other cause of death is found

It can be caused by things like pauses in breathing during a seizure which cause death

17
Q

In which populations is epilepsy more common?

A

Downs Syndrome (8%)
Tuberous sclerosis (80-90%)
Angelman Syndrome (>80%)
Fragile X syndrome (13-40%)

18
Q

What is Tuberous sclerosis?

A

A genetic disease that causes non-cancerous (benign) tumours to grow in the brain and several areas of the body, including the spinal cord, nerves, eyes, lung, heart, kidneys, and skin

19
Q

What is Angelman Syndrome?

A

A genetic disorder that causes delayed development, problems with speech and balance, intellectual disability, and, sometimes, seizures

People with Angelman syndrome often smile and laugh frequently, and have happy, excitable personalities

20
Q

What is Fragile X syndrome?

A

A genetic condition that causes a range of developmental problems including learning disabilities and cognitive impairment

Only males often affected

Affected individuals usually have delayed development of speech and language by age 2

21
Q

What is Doose syndrome?

A

A seizure disorder characterized by frequent myoclonic and myoclonic-atonic seizures

22
Q

What is West syndrome?

A

Previously known as Infantile spasms syndrome

Children have seizures and cognitive and developmental impairements

23
Q

What is benign sleep myoclonus?

A

A self-limiting condition characterised by neonatal onset myoclonic jerks during non-REM sleep

24
Q

What is Sandifer syndrome?

A

Unusual movements of your child’s head, neck and back

Can be an epilepsy mimic

25
Q

What is cerebral palsy?

A

Most common motor disability in children

Causes motor, balance, and coordination problems because of damage to those areas of the brain

26
Q

What is the difference between cerebral and Bells palsy?

A

Bell’s affects half of face

Cerebral affects whole body

27
Q

What are some paediatric signs of cerebral palsy?

A
  • Delayed milestones
    Eg. not sitting by 8 months or not walking by 18 months
  • Seeming too stiff or too floppy (hypotonia)
  • Weak arms or legs.
  • Fidgety, jerky or clumsy movement
  • Random, uncontrolled movements
  • Muscle spasms
  • Shaking hands (tremors)
28
Q

What is muscular dystrophy?

A

A group of diseases that cause progressive weakness and loss of muscle mass

29
Q

How does Duchenne’s muscular dystrophy progress?

A

Affects only boys, girls would get milder version

Need wheelchair by 12 yrs. By 20yrs they develop breathing problems. Die during 30’s

30
Q

What is myotonic dystrophy?

A

Progressive weakness and wasting of muscles and it affects the electrical conductive system of the heart, lungs, swallowing, bowels, eyes, and brain

Patients live to their 40’s and usually die from respiratory or cardiovascular failure

31
Q

What is Facioscapulohumeral muscular dystrophy?

A

Affects both men and women
Causes progressive weakness and wasting of face, shoulders, and humorous

Sign: sleeping with eyes slightly open, inability to squeeze eye tightly, inability to purse lips

32
Q

What is Becker muscular dystrophy?

A

Like Duchenne’s jut less severe

Causes delayed walking and muscle cramps with exercise

Some may need wheelchair by 50yrs, but most have a normal lifespan

33
Q

What is Limb-girdle muscular dystrophy?

A

Causes muscle weakness in hips, thighs and arm, back pain, and heart palpitations

Progress differently from person-to-person

34
Q

What is spinal muscular atrophy (SMA)?

A

A genetic condition where the motor nerve cell in the spinal cord are attacked which causes weakness and atrophy of the spinal muscles

Affects child’s ability to crawl, walk, sit up, and control head movements

In severe cases, can affect breathing and swallowing

35
Q

Which medication is prescribed for absence seizures in children?

A

Ethosuximide in girls of child bearing age
Sodium valproate when not child bearing

Lamotrigine can be used to increase effectiveness

36
Q

Why can’t carbamazepine be used in childhood absence seizures?

A

Because it can aggravate them
