Fronto-temporal In the early experience, a person’s personality and behaviour will be affected rather then their memory.
Types of dementia that
affect the frontal and / or
temporal lobes Familial Fronto- temporal dementia

Research has indicated that there may be a problem with some of the genes on chromosomes 3 and 17.

Fronto-temporal dementia relates to a number of different dementias that include Pick’s disease, semantic dementia and primary progressive aphasia.

It is still the most common form of CJD. Sporadic nvCJD iatrogenic CJD Posterior cortical atrophy (PCA)
Progressive supranuclear palsy

Sometimes known as Steele-Richardson-Osliewski syndrome.

It affects the brain stem and adjacent areas, and some of its early symptoms resemble those of Parkinson's disease.

One striking symptom is paralysis affecting eye movements and problems with vision. Although there are likely to be problems with more complex and abstract thought, the person will remain aware of what is going on around them.

Because a prion is infectious this means it can be spread in different ways. It has been suggested that it could be passed through infected meat.

Familial Inherited CJD is caused by a faulty gene, and is passed down from parents to their children. It's very rare; there are only a few deaths from it in the UK every year.
