Hi Mita, right now your father is having sani mahadasha and rahu antardasha,rahu antardasha got started in june 2007 and it will end in septemeber 2009.you can expect 50 percent releif after september of this year.moon's position tells about the mind of the person.Moon in your father's horoscope is badly afflicted with rahu,ketu,which makes him have more psychological problems during rahu dasha.Close affliction of less than 1 degree between rahu,ketu and moon is indicated in the chart,which makes the person have more psychological problems.I can understand how the life will be with saturn as 8th lord and its maha dasha is running now.Taking medical treatment,propotiating rahu,ketu,mercury,mars,moon is good for him.Right now Rahu,ketu pooja in Srikalahasti is good for him,which gives lots of releif.
Otherwise please be patient till september 2009.Till 2012,he will have sani mahadasha.after that will have budha mahadasha,a little bit better than sani dasha. If you got any more questions please visit my website Astroforetell.com
All The Best For You And Your Father,
Swarna.
