cbd illness

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

CBD occurs when brain cells in certain parts of the brain are damaged as a result of a build-up of a protein called tau.

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.

The diagnosis must be made or confirmed by a consultant with expertise in CBD. This will usually be a neurologist (a specialist in conditions affecting the brain and nerves).

Outlook

Symptoms can include:

Most cases of CBD develop in adults aged between 50 and 70.

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.

What causes CBD?

You may need to have a brain scan to look for other possible causes of your symptoms, as well as tests of your memory, concentration and ability to understand language.

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.

Movement difficulties

Corticobasal Degeneration (CBD) is a rare type of parkinsonism that affects people from the age of 40, typically between the ages of 50 to 70. It tends to affect one side of the body more than the other initially, gradually spreading over a few years.

Diagnosis

CBD occurs when cells in specific parts of the brain – the cortex and basal ganglia – are damaged as a protein called tau builds up and over time causes harmful clumps. In normal brains, tau is broken down to avoid a build-up, but in CBD this does not happen.

Symptoms

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