Hi,
It does sound as though your mom is responding some to the medication. Drowsiness is not unusual. I am very close to your mom's age, and when I started on sinemet did so on the same dose.

I had symptoms for quite a while prior to being tried out on medication and initially though it did feel good that I could do some things again I do not think others could see the improvements I felt. It felt like it took time for my dopamine starved brain to start to get back into balance.

The little improvements you feel you can see may be a positive sign for pd. But that is for your mom and her neuro to decide. I wanted to say that overall I have had way more improvement since those early days, though it did take time, and some effort to get things working better for me. Today I am a lot more functional than I was then, some of the improvements surprised me as I had not noticed everything that pd had been taking away from me.

It was crucial to my improvement that I understood what was happening to me, this forum was an immense help, supportive and informative at the same time.

I hope if this is pd you are seeing in your mom, that she too finds a similar improvement, and wish you both the best in getting things sorted out.

Keep in touch and let us know how things are going.

Lindy
