cbd disease

Changes in personality, such as apathy, irritability, and decreased interest in things previously enjoyed may be noticed by family and friends.

There is currently no cure or treatment to stop CBD’s progression but medication and various therapies can relieve symptoms and improve quality of life.

CBD has similarities with Progressive Supranuclear Palsy (PSP). Some people with CBD go on to develop PSP, and vice versa.

Causes

Diagnosis is usually based on the pattern of symptoms experienced and the exclusion of other conditions that may cause similar symptoms, such as Parkinson’s or stroke. Unfortunately, as with Parkinson’s, there is no single test or scan to diagnose CBD.

Cognitive and behavioural changes: thinking may become impaired, leading to memory problems and difficulty understanding and interpreting communication. It may also be difficult to carry out complex tasks that require planning ahead.

Acknowledgement

CBD is a very individual condition and the symptoms each person experiences vary. As CBD is a progressive neurodegenerative condition, symptoms gradually become worse over time.

As CBD reaches an advanced stage, muscle stiffness will continue to get worse. People with the condition may lose the ability to move 1 or more limbs. Some people are unable to walk and need a wheelchair or assistance to transfer (such as help getting into and out of bed).

As CBD progresses, it may eventually start to cause problems in your other limbs.

CBD typically affects one of the limbs at first. This is usually a hand or arm, but sometimes a leg.

The condition tends to develop gradually, which means it can be mistaken for another condition at first – such as Parkinson’s disease, dementia or a stroke.

Mid-stage symptoms

It’s also common for someone with CBD to experience personality changes, such as becoming apathetic, irritable, agitated or anxious.

The symptoms typically become more severe over several years, although the speed at which they worsen varies.

Other problems people with advanced CBD can experience include:

Early symptoms

Some people also develop problems with walking and co-ordination.

Some of the main symptoms of CBD are outlined below. Most people with the condition won’t experience all of these.

Difficulty swallowing can cause choking, or inhaling food or liquid into the airways. This can lead to pneumonia, which can be life-threatening.

There’s no single test for CBD. Instead, the diagnosis is based on the pattern of your symptoms. Your doctor will try to rule out other conditions that can cause similar symptoms, such as Parkinson’s disease or a stroke.

CBD is caused by increasing numbers of brain cells becoming damaged or dying over time.

Outlook

Good care and assistance can help someone with CBD be more independent and enjoy a better quality of life, but the condition will eventually put them at risk of serious complications.

The symptoms of CBD get gradually worse over time. They are very variable and many people only have a few of them.

If you have CBD, your clinical team will pass information about you on to the National Congenital Anomaly and Rare Diseases Registration Service (NCARDRS).

Diagnosing CBD

CBD has been linked to changes in certain genes, but these genetic links are weak and the risk to other family members is very low.

One limb is usually affected at first, before spreading to the rest of the body. The rate at which the symptoms progress varies widely from person to person.
