Help deciphering cause of death

[SingaporeSlinky]

Can anyone help read the causes of death please? I can only make out
1a xx thrombosis
b xx
certified by etc.

Many thanks.

Hmmm - b is Arteriosclerosis. Will keep puzzling over a.

Cerebral thrombosis
Arterio sclerosis
certified by G Cassie MB

Ie a stroke

Cerebral thrombosis?

Ah, ok thank you very much!

Also, what would ‘otherwise’ for a man mean, on a death certificate? For example, John Smith, otherwise Jones.

That he was known by two names eg perhaps he had a stepfather's and his real father's names at different times.

It’s surely a funny looking D in MD?

2 names could be from unmarried mother + father, or stepfather

If it's UK, it is far, far more likely to be MB (bachelor of medicine).
