Q

ALS - role of investigations

A

ALS is a clinical diagnosis

Investigations are used to exclude differentials and detect LMN disease in limbs that are clinical unaffected

Exclude differentials

  • Imaging (area of spine with suspected lesions, brain if bulbar signs)
  • Nerve conduction and blood tests if peripheral nerve signs

Asses limb involvement is asymptomatic limbs
- EMG

98
Q

Duchenne muscular dystrophy - inheritance

A

X-linked recessive

30% are spontaneous

99
Q

Becker muscular dystrophy s Duchenne

A

Becker presents later, is less severe and has better prognosis

Both are X-linked recessive

100
Q

Myasthenia gravis - initial investigations

A

Antibodies:

  • Anti-AChR
  • Muscle-specific tyrosine kinase (MuSK) antibodies

Serial FVC and NIF - if suspected MG crisis

EMG

CT chest - performed at diagnosis to detect thymoma (15%) or thymic hyperplasia (75%)

101
Q

Lambert Eaton vs Mysasthenia Gravis

A

Lambert Eaton:

  • Leg weakness before ocular involvement
  • Autonomic dysfunction (dry mouth is most common/metallic taste)
  • Areflexia
102
Q

Neurofibromatosis type 1

Inheritance
Clinical features

A

Von Recklinghausen’s disease

Inheritance: Autosomal dominant

Clinical features:

  • Cafe-au-lait spots

  • Neurofibromas
  • Lisch nodules (small hamartomatous nodules in the iris)
  • Neoplasia (CNS, phaeo, AML)

Q

Cafe-au-lait spots

Causes

A

Neurofibromatosis (I and II)
McCune-Albright

104
Q

Neurofibromatosis type 2

Inheritance
Clinical features

A

Inheritance:
- Autosomal dominant (50% de novo)

Clinical features:

  • Bilateral acoustic schwannomas are characteristic (first sensorineural hearing loss, the tinnitus, then vertigo)
  • Cafe-au-lait - typically fewer than in NF1
  • Bilateral cataracts
105
Q

Pathophysiology
Clinical features

A

Tubular cavity in the central canal of the cervical cord

Clinical features:

  • Hand wasting (claw hand)
  • Absent upper limb reflexes
  • Charcot joints (shoulder, elbow)
106
Q

Friedrich’s ataxia

Clinical features

A

Mitochondrial disease

  • Bilateral cerebellar signs
  • Leg wasting and areflexia
  • Optic atrophy
  • HOCM
  • DM - hyperglycaemia
107
