What is Parkinsonian Dementia?

Parkinsonian dementia, also known as Parkinson’s disease dementia (PDD) or Parkinson’s dementia, is a type of dementia that affects patients who have previously been diagnosed with Parkinson’s disease. It’s not fully understood what causes PDD, but it’s thought to be due to abnormalities with Lewy body protein deposits in the brain. It is most common in people who are over the age of 65.

A person with PDD may experience a range of symptoms, including hallucinations, tremors and shaking, muscle stiffness, issues with concentration and memory, changes in mood, and problems sleeping. Symptoms vary from person to person, as does their severity and the rate at which they progress. Generally, symptoms will get worse over time and the patient may eventually lose the ability to live independently.

At Dementech Neurosciences, our team of dementia specialists offer a multi-faceted approach to treating PDD. We have a number of in-house clinicians who can support you from the diagnosis through to treatment, helping you to mitigate your symptoms and live a normal, independent life for as long as possible.

Parkinson’s Dementia Symptoms

PDD affects a person’s cognitive and motor skills, and the symptoms will gradually get worse over time. The first signs of cognitive decline typically occur approximately one year after an initial Parkinson’s disease diagnosis.

There are a number of common symptoms people with PDD may experience. Not everyone will have the same symptoms, but common characteristics can 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

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 dementia, it’s important to speak to a neurologist to find out what could be causing your symptoms. 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 for.

Parkinson’s Dementia Diagnosis

Diagnosing Parkinsonian dementia isn’t as simple as carrying out a single test. Instead, you may need to undergo multiple scans and assessments in order for us to make the right diagnosis. This is because PDD is similar to Lewy body dementia (DLB). They both share similar symptoms but are, in fact, different.

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 symptoms started roughly a year after a Parkinson’s disease diagnosis, Parkinson’s disease dementia is often the diagnosis 
  • If cognitive impairment symptoms started approximately a year before physical motor symptoms, the diagnosis is often dementia with Lewy bodies

For a diagnosis, you will need to attend a consultation where you will speak to one of our private dementia consultants about your symptoms, as well as your previous medical history. They may get you to complete some cognitive tests by asking you a series of questions.

After this, you may need to go for some other tests, such as blood tests or an MRI scan. These tests will rule out any other brain conditions that may be causing your symptoms. We endeavour to get your results to you within 48 hours and can also give a copy, along with our diagnosis, to your GP.

We use cutting-edge technology to assess the severity of cognitive deficits in people with Parkinson’s dementia. This enables us to provide an early diagnosis of cognitive impairment and effectively manage it early on.

Parkinson’s Dementia Treatment

Unfortunately, there is no cure for Parkinson’s dementia, and there is no treatment that can slow the rate at which the condition destroys brain cells. Instead, treatment is focused on mitigating symptoms and aiming to help the patient live as independently as possible for as long as possible.

At Dementech Neurosciences, we offer a multidisciplinary approach to treating the symptoms of Parkinsonian dementia. We have a comprehensive dementia team who can offer a mixture of clinical and therapeutic treatments. Common treatments for PDD may include:

  • Cholinesterase inhibitors: These are a type of Alzheimer’s medication that can minimise cognitive decline and help manage symptoms relating to hallucinations, memory, judgement, mood and sleep issues 
  • Antidepressant medication: People with PDD sometimes become anxious and depressed, so antidepressant medication can sometimes help to mitigate these symptoms
  • Physiotherapy: One of our in-house physiotherapists can work with you to manage the physical motor symptoms of Parkinson’s disease 
  • Speech and language therapy: We will work with you to maintain your communication abilities 
  • Psychiatry: Our specialist psychiatrists can work alongside psychologists to monitor your cognitive function

Clinical Trials

At Dementech, we also offer patients the opportunity to participate in clinical trials testing novel pharmacological intervention, before they become available to the public, aiming to delay the progression of PDD.
