48
Multiple sclerosis further investigation
Diagnosis of exclusion Evoked potentials- measure electrical activity in brain in response to visual, auditory or somatosensory stimuli
49
Multiple sclerosis pathology
- Immune system attacks myelin sheath and causes communication problems between brain and rest of body - Can eventually cause permanent damage or deterioration of nerve fibres
50
Cautions of multiple sclerosis
- May also develop muscle stiffness/spasm, weakness or paralysis, problems with bladder Wide range of symptoms therefore difficult to predict
51

67
Hyperthyroidism further investigation
Blood tests- elevated calcium levels X-ray bone density loss, bone cysts in rare cases
68
Hyperthyroidism pathology
Parathyroid gland produces PTH in response to low calcium levels, PTH increases calcium absorption in gut, activates osteoclasts to break down bone, releasing calcium into blood stream - Where parathyroid gland over produces parathyroid hormone in bloodstream - Parathyroid healps maintain right balance of calcium in blood stream and tissues - Especillay important for nerve and muscle function as well as bone health - Primary- enlargement of parathyroid gland casues overproduction of parathyroid hormone - Secondary- result of another disease
69
Cautions of hyperthyroidism
Avoid high calcium diet- such as dairy Avoid Vit D supplements
70

75
Cautions of hypothyroidism
Avoid low calcium diets Cautions of vit D and calcium supplements if HX of kidney stones/renal failure as this increases risk
76
Hypothyroidism management
- Supplements can bring calcium and phosphorus levels to normal range Regular blood tests to check levels
77
Parkinson's aetiology
- Breakdown of neurons - Mainly due to loss of neurons that produce dopamine in brain - When dopamine levels decrease, it causes atypical brain activity, leadsing to impaired movement and other symptoms of Parkinson’s
78
