Dear Divya Ji,
His planet Mercury is debilitated and with Sun and Ketu. His Ascendant Lord Venus is also not well placed. So, speech delay and hypertension may always be there in his life. Only you can expect some improvement.
This is a big problem. If you want to know about Remedies that can help him, then please come through PAID consultation. I will check more and suggest you the possible remedies.
Thank and Regards,
Astrologer Sourav
