What are two examples of common major neurodegenerative disorders?

 Choose 2 answers. 

A. Atherosclerosis is the build-up of plaques in the arteries, leading to narrowed and hardened arteries, not dilation and weakening.

B. Varicose vein involve the swelling and twisting of veins, usually in the legs, due to valve failure, not the dilation of a blood vessel wall as in an aneurysm.

C. Aneurysm is the local dilation or bulging of a blood vessel due to a weakening of the vessel wall, which can lead to rupture and serious complications.

D. Thrombophlebitis is inflammation of a vein associated with clot formation, not the dilation of a blood vessel.

A. Cerebral Aneurysm is not a neurodegenerative disorder; it is a localized dilation of a blood vessel in the brain that can lead to haemorrhage.

B. Diabetic retinopathy is a complication of diabetes affecting the eyes, not a neurodegenerative disorder.

C. Multiple sclerosis (MS) is a major neurodegenerative disorder where the immune system attacks the protective sheath (myelin) that covers nerve fibres, leading to communication problems between the brain and the rest of the body.

D. Bell's Palsy is a condition that causes sudden, temporary weakness or paralysis of the facial muscles, but it is not a neurodegenerative disorder.

E. Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a neurodegenerative disorder that affects motor neurons, leading to muscle weakness and atrophy.

F. Cerumen impaction is the build-up of earwax and is not related to neurodegenerative processes.
