There are no blood tests that can diagnose PSP, although brain scans may reveal a Hummingbird sign in some people with PSP. Generally, tests and scans will be used to rule-out other conditions. It is common for people with early symptoms of PSP to be misdiagnosed with Parkinson’s due to similar symptoms, such as slowness of movement.

Two of the key signs indicating the need to review a diagnosis of Parkinson’s and consider PSP are a limited response to Parkinson’s medication and changes in the movement of the eyes. Some people with PSP are also misdiagnosed with dementia due to problems they may experience with slowness of thinking.

Because PSP is rare, many doctors are not even aware of the condition and do not know what symptoms to look for, although this situation is improving. It is important to see a neurologist, who is a doctor specialising in brain conditions. People with PSP should visit their neurologist regularly for ongoing treatment and advice. If possible, see a neurologist with expertise in movement disorders, as they are more likely to be up-to-date with the latest advances in treatment and management.

To help spot the signs and symptoms of PSP, Fight Parkinson’s would like to share this video on spotting the red flags of Progressive Supranuclear Palsy by the PSP Association in the UK.

If you or a loved one is experiencing one or more of these symptoms, please visit your GP for guidance.
