Parkinson’s Dementia Disease Diagnosis and Treatment
At Dementech Neurosciences, our specialist neurologists and dementia consultants provide expert assessment, diagnosis and personalised treatment for people living with Parkinson’s disease dementia. Our tailored care plans focus on managing cognitive and physical symptoms, supporting independence and improving quality of life, with ongoing guidance for patients and their caregivers.
Parkinsonian dementia, also called Parkinson’s disease dementia (PDD) is a form of dementia that develops in patients who have previously been diagnosed with Parkinson’s disease. While the exact cause isn’t fully understood, it is believed to result from abnormal deposits of Lewy body proteins in the brain. PDD most commonly affects individuals over the age of 65.
Parkinson’s dementia impacts both cognitive and motor abilities, with symptoms typically worsening gradually over time. Early signs of cognitive decline often appear around one year after a Parkinson’s disease diagnosis.
While symptoms can vary from person to person, common experiences may include a mix of physical and behavioural changes. Some of the most frequently observed characteristics include:
- Changes in your ability to recall memories
- Trouble concentrating on tasks
- Lapses in judgement and critical thinking
- Issues trying to process and interpret visual cues
- Vivid hallucinations where you may see, smell, feel or hear things that aren’t there
- Experiencing delusion, specifically paranoia
- Changes to your mood, such as increased irritability or feelings of apathy
- Feeling anxious and/or depressed
- Sleep-related issues, such as rapid eye movement (REM) sleep disorder or sleep disturbances
- Feeling drowsy during the day
- Losing your appetite
- Parkinson’s symptoms, such as uncontrollable tremors or shaking, muscle rigidity, shuffling, and movement issues
- Difficulties communicating or speaking with others
If you have any of the above symptoms, it doesn’t necessarily mean you have Parkinsonian dementia. It’s common for people with motor issues like Parkinson’s disease to experience some decline in their cognitive abilities.
Similar cognitive impairment occurs in Atypical Parkinsonism such as progressive supranuclear palsy (PSP), multiple system atrophy (MSA), and corticobasal syndrome (CBS). Huntington’s disease (HD) also causes a decline in thinking and reasoning skills, including memory, concentration, judgement and ability to plan and organise.
There is no cure for Parkinson’s disease dementia, but symptoms can usually be managed effectively for a number of years.
If you think you have any symptoms of Parkinson’s dementia, it’s important to speak to a neurologist to find out what could be causing them. Early intervention is the best form of treatment, and whilst PDD can’t be cured, it may be possible to minimise the severity of symptoms and prolong how long you can live independently.
Diagnosing Parkinsonian dementia (PDD) is not straightforward and usually requires a combination of assessments and scans. This careful approach is necessary because PDD shares many symptoms with dementia with Lewy bodies (DLB), even though the two are distinct conditions.
The Difference Between PDD and DLB
Due to the similarities between both conditions, there are two main guidelines your neurologist will follow to determine a PDD diagnosis:
- If cognitive decline appears roughly one year after a Parkinson’s disease diagnosis, Parkinson’s disease dementia is usually the diagnosis.
- If cognitive impairment begins approximately one year before the onset of physical motor symptoms, dementia with Lewy bodies is more likely.

Parkinson’s Dementia Disease Diagnosis and Treatment at Dementech

At Dementech Neurosciences, we take a thorough and precise approach to diagnosing Parkinson’s disease dementia (PDD). Your assessment begins with a consultation with one of our specialist dementia consultants, who will review your symptoms and history in detail. You may also complete cognitive tests designed to evaluate memory, attention, and thinking skills.
Depending on your individual case, additional tests such as blood work or an MRI scan may be recommended to rule out other conditions that could be contributing to your symptoms. We aim to deliver your results within 48 hours and can provide a detailed report, including our diagnosis, directly to your GP.
By combining expert clinical insight with cutting-edge technology, we are able to assess the severity of cognitive changes early. This allows us to diagnose Parkinson’s dementia confidently and implement an effective management plan from the outset, helping you maintain independence and quality of life for as long as possible.

“Dementech Neurosciences is a relatively new clinic specialising in the scientific assessment and treatment of Parkinson’s Disease. It represents a significant development in the treatment of Parkinson’s and has done a great job of establishing itself and its reputation in a short period of time. The premises are extremely well situated in central London, the consultant neurologists are all at the top of their field in their specialisation of the treatment of Parkinson’s Disease, and the clinical and administrative staff are of a similar standard. The atmosphere of the clinic is positive and the results, in the short period of time I have been able to assess, have been similarly positive.”

“Have had nothing but kindness and professionalism from Dementech and all their staff. From their initial guidance by Shakeela, through to staff conducting the MRI tests and Dr. Lucio D’Anna for his expertise clarity of explanation, compassion and consideration. Special mention to Zobia, who saved the day with her quick thinking that helped my mother-in-law to obtain extended care. Overall a perfect experience. Cannot recommend them enough.”
