Q

Aetiology of MS

A
  • Genetic - genetic predisposition, HLADR2, exposed to particular virus, develops a immune response to virus
  • Environmental - linked to low vitamin D
  • More common in women 20-40 years old
    o- Exposure to Epstein virus and human herpes virus can lead to onset of MS

Q

What are the mechanisms of MS?

A

Oligodendrocytes - release of types of molecules - interleukin, TNF act on the area and, express some cell adhesion areas
When people are exposed to a particular antigen (viral agent)
Normal process = macrophages engulf the antigen and then express the cell on its cell membrane - phagocytosis (engulfs the virus) and when it expresses the cells on the cell membrane, the Helper T cells

Q

What is relapsing remitting MS?

A

Flare up as a result of increased deteriation of symptoms, person returns to somewhat improved level of functioning - it’s a progressive decline in function

A

Starts same as relapsing remitting then the Demyelination progresses to a constant state

Q

What are the complications of MS?

A
  • Muscle stiffness or spasms
  • Severe weakness or paralysis, typically in the legs
  • Problems with bladder, bowel, or sexual function
  • Cognitive problems, like forgetfulness or word finding difficulties.
  • Mood problems, such as depression, anxiety, or mood swings
  • Seizures, though very rare

Q

What is the impact on OP for MS?

A

Gradual loss of independence in ADLs, and IADLs, and meaningful occupation due to progressing conditions and symptoms
- Balance
- Mobility
- Visual issues
- Coordination

16
Q

How many types of fatigue are there in MS? Name each of the types of fatigue that might be experienced by a person who has MS.

A

2 types
Primary fatigue – fatigue caused by nerve damage
Secondary fatigue – fatigue caused by factors related to MS

17
Q

What is diplopia?

A

MS can also have an effect on parts of your brain that control how your eyes move. This can cause symptoms of double vision or wobbly vision

18
Q

What is ataxia and how does MS cause ataxia?

A

Ataxia is a lack of coordination of muscle movements which can appear as clumsiness, unsteady gait, impaired eye and limb movements, speech problems and sometimes dizziness

19
Q

Why is a person with MS intolerant to heat, and what are the functional implications of heat intolerance and mood changes?

A

being overheated slows down the messages passing along nerves, which have already been damaged by the loss of myelin and this gives rise to increased symptoms. In some cases, there’s a lesion in a part of the brain that controls temperature regulation in the body.

20
Q

What is Romberg’s test?

A

determines if your balance issues are related to the function of your dorsal column by removing the visual and vestibular components that contribute to maintaining balance.

21
Q

What is the difference between a cognitive impairment and a flat affect?

A
  1. A person with a flat affect is note to show diminished or lack of normal emotion, This could include facial expressions, monotonous voice, or reports that they are apathetic or ‘don’t care’
  2. A cognitive impairment involves deterioration in the ability to process, learn, and remember information. This can be evident in difficulty in carrying out tasks that require thinking, planning, and memory.
22
Q

What is myelin and its role in MS?

A

Myelin is the sheath that surround nerves in the body. Myelin allows conductivity along the nerves and damage to it can interrupt motor or sensory message between the body and the brain. In MS breakdown of the myelin occurs ‘demyelination’ and this causes inflammation. As the inflammation builds up scar form resulting in ‘scleroses’. This results in long term nervous damage and a deterioration in motor and sensory function.

23
Q

At what age is the onset of MS most prevalent?

A

20-50 years

24
Q

What does MRI stand for and what are the white areas on the image?

A
  • MRI stands for magnetic resonance imaging.
  • The white areas on the scan are plaques/ lesions/ scleroses that occur with MS. These are areas of the brain that are inflamed as a result of demyelination.
25
Q

What is the difference between MS related neuromuscular fatigue and lassitude?

A

Lassitude is an overwhelming tiredness that comes on for no obvious reason whilst neuromuscular fatigue is caused by inefficient nerve conduction. To stop or ‘short circuit’ the fatigue and periods of rest or inactivity need to be taken. Strategies to do so include staggering social or work commitments

26
Q

How could individuals with MS adjust their lifestyle to minimise neuromuscular fatigue and lassitude?

A
  • keep cool
  • avoid hot conditions (showers)
    avoid excessive physical strain
  • maintain healthy weight
27
Q

what are the early symptoms of MS?

A
  • Blurry vision
  • Increased fatigue
  • Decreased attention
  • Pins and needles
  • Difficulty in bladder control
  • Impaired balance
