Nerval disorder (weakness) Guide me.

Dear Sir /Madam,I am 34 years old .I was diagnosed with BPAD in the year 2004.And still now I am on medication with mood stabilzers.Unexepectedly I developed chicken pox in the year 2005 which led to Post Chicken pox cerebelities making my nervous system weak .My motor activities with speech ,hand eye coordination was drastically damaged.The tremors in the hands are miserable to handle routines.All these years, Physiotheraphy proved futile,with micro level improvement.And the feedback from the doctors reveal that the Psychiatry medicines are stalling the improvement in the nervous system.My query is that ,can I go for an alternative treatment for the nervous problem(say ayurvedic) simultaneously continuing the Psychiatry medicines.In doing so, does it have any side effect on my mental or physical health.Kindly guide me.
