What Causes Loss Of Consciousness With Right Thalamic Bleeding?

Hi, My father aged 58 years had a sudden onset of loss of consciousness. He is diagnosed to have Right thalamic bleed with intraventricular extension, underwent external ventricular drainage procedure in view of ventriculomegaly, subsequently his sensorium has improved with spontaneous eye opening and repeat CT scan done showed resolution of right thalamic haematoma. Now he is weaned off the ventrilator support, but my fear is he is still in the ward and some time he is active and some times he is very drowsy, could you kindly advise me for further treatment, it is since 40 days.....
