I have enough letters for this one to be TACKING, but the parsing is beyond me so that may be wrong.

It's given to Alzheimer's sufferer, certain for treatment (7) 

I have TAC?IN? 
 

Thanks

Tacrine, anag certain 

[cashier]

Tacrine anag certain and a drug for Alzheimers.

[scorpiojo]

Tacrine is used to treat the symptoms of mild to moderate Alzheimer's disease

[Toorak]

Tacrine - anagram of certain

[FleshpotsOfDevon]

Thanks! I'd fiddled with a few anagrams of certain but nothing stood out, especially when I'm not familiar with the word.

Last one - 34a) Aaron’s converted and no longer bears name as part of old Jewish sect (10) I have N?SAR?SAN. Thanks.

Nasoreans?

[ProfessorMaisie]

Anag of ''Aaron's'' followed by EANS = 'bears' (young).

There's an anagram following the 'Chambers' ref telling you where to find it in Chambers.

^ Nasareans??

[ProfessorMaisie]

Youve missed an 'a' elliemay1, but that's just about it.
