Potential Target for Treating Common Form of Early-Onset Dementia Identified. UCLA scientists have discovered that a key signaling pathway plays an important role in the brain disorder frontotemporal dementia (FTD) and may offer a potential target for treatment. The journal Neuron publishes the findings in its Sept. 22 edition. ScienceDaily (Sep. 22, 2011)

Humor as Effective as Medication in Treating Agitation in Dementia. Humor therapy is as effective as widely used antipsychotic drugs in managing agitation in patients with dementia — and avoids serious drug side effects, a new study shows. ScienceDaily (Sep. 23, 2011)
- Human genetics study identifies the most common cause of ALS and dementia. Scientists have made an exciting breakthrough in unraveling the genetic basis of two debilitating neurodegenerative disorders, amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

- Alzheimer disease: Transport protein ABCC1 plays key role in clearing beta-amyloid from brains of mice.
Alzheimer disease (AD) is the most common cause of dementia among older people. One of the main features of AD is the presence in the brain of abnormal clumps of the protein fragment beta-amyloid. Researchers have now identified a way to reduce the amount of beta-amyloid in the brains of mice with a disease that models AD, providing hope that a similar approach could benefit patients with this devastating condition.
