How can my 71-year-old father manage his Parkinson’s disease?

Question

Hello doctor,

My 71-year-old father has had Parkinson’s disease for three years, and his symptoms are progressing much faster than we initially expected. His tremors have become so severe that he can no longer feed himself, write his name, or button his shirts without help. Carbidopa-Levodopa helps with stiffness but causes unpredictable freezing episodes, during which he suddenly becomes unable to move without warning.

He has fallen seven times in the past month, as his balance continues to deteriorate rapidly. His voice has become so quiet and mumbled that we constantly struggle to hear him, which frustrates everyone immensely. His sleep is also disrupted by violent nightmares, during which he acts out his dreams and accidentally hits my mother, leaving her bruised.

The neurologist mentioned deep-brain stimulation (DBS) surgery, but we are terrified of the potential risks and complications given his age. His independence is disappearing, and he is profoundly depressed about feeling like a burden and losing his dignity.

Are there any newer medications or combination therapies that can slow disease progression more effectively? We are desperate to preserve his quality of life.

Please advise.

Thank you.

Hello,

Welcome to icliniq.com.

I can understand your concern. I am truly sorry to hear about what your father and your family are going through.

Parkinson’s disease can be heartbreaking to witness as it gradually takes away independence and confidence, and it is completely understandable that you are all feeling overwhelmed. From what you describe, your father appears to be in an advanced stage of the disease, with motor fluctuations, freezing episodes, severe tremor, balance loss, and REM (rapid eye movement) sleep behavior disorder, causing violent dream enactment. These symptoms are emotionally and physically exhausting, both for him and for your mother as his caregiver.

While Carbidopa-Levodopa remains the gold standard treatment for Parkinson’s, its effectiveness often fluctuates over time, leading to the “on-off” phenomena you are observing. However, there are additional medications that can be combined to help smooth out these fluctuations, such as COMT (catechol-O-methyltransferase) inhibitors (Entacapone, Opicapone) and MAO-B (monoamine oxidase-B) inhibitors (Rasagiline, Safinamide), which prolong the effects of Levodopa. Amantadine can also help reduce dyskinesias and, in some cases, improve freezing. Extended-release formulations or the Levodopa-Carbidopa intestinal gel (Duopa) may provide steadier symptom control in advanced cases.

Regarding deep brain stimulation (DBS), while age slightly increases surgical risk, many patients in their seventies still experience significant benefits when carefully selected, particularly those whose symptoms respond to medication but who have unpredictable “off” periods. A thorough pre-surgical evaluation, including neuropsychological testing and brain imaging, is essential to determine candidacy safely.

Beyond medications and surgery, supportive therapies can make a meaningful difference. Physical therapy can help with balance and gait; speech therapy (such as the Lee Silverman voice treatment) can improve voice and swallowing; and occupational therapy can assist with adapting daily activities. For vivid nightmares and dream enactment, Clonazepam or Melatonin at bedtime can be effective under a neurologist’s supervision.

Addressing depression is equally important, both for quality of life and because mood improvements can positively affect motor symptoms. Many patients benefit from SSRIs (selective serotonin reuptake inhibitors) or dopamine agonists with antidepressant properties.

Your and your mother’s support is invaluable, but you should not have to carry this burden alone. Discussing a referral to a multidisciplinary Parkinson’s clinic or a local support group with his neurologist can provide crucial emotional and practical help. Although the disease cannot yet be stopped, a comprehensive approach, combining medical, surgical, and supportive therapies, can still restore a sense of dignity, communication, and comfort for your father.

Take care, and I hope this was useful.

Thank you.
