2£®Q: When should patients begin to take Capsule GCs and for how long time? Should Capsule GCs be combined with other medicines?

A: Capsule GCs may be given to patients at the early phase. One treatment course is 3 months. Patient may take Capsule GCs for long time. There is no absolute indication for combined medication, and clinical practice didn¡¯t prove any counteraction of Capsule GCs to other medicines either.

3. Q:VD usually happens in rehabilitation phase, at this time some neurons are already dead, the function of dead neurons can not be reversed. The main function of Capsule GCs is anti-apoptosis. Will Capsule GCs be accepted to treat VD?

A:Indeed, the dead neurons may not revive. However, besides the function of preventing neuron from apoptosis, Capsule GCs also (a,) promotes growth of new axons. (b,) stimulates the stem cells to differentiate into new neurons. These effects help the recovery of neuro-function.
4£®Q:How is the probability of hypertension and diabetes to developVD?

A:Some studies revealed that the annual rate of VD in normal people is 0.7%, while 1.6% in people with hypertension.The rate of VD in people with hypertension combined with heart disease will be as 3 times high as in normal people. The rate of VD in people with hypertension combined with diabetes is 6 times higher. 20% VD patients suffer from diabetes.
