Hi, Thank you for posting your query. Parkinson s disease (PD) is a degenerative disease of the brain, and it requires medications lifelong. Despite medications, the disease continues to get worse in severity leading to disability. Syndopa (levodopa) is the main medication used for treating PD, as it provides dopamine (which is deficient in brain of PD patients). Postural giddiness- giddiness that occurs on standing- is a common side effect of syndopa. To avoid this, she should be sitting up slowly, from a sleeping posture, and then try to get up slowly and walk. If she still has side effects, the dose of syndopa may be reduced.
