How infection can lead to psychiatric problems

Scientists using mice have discovered how early exposure to a common type of bacterium can lead to psychiatric disorders. PANDAS (Paediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infection not the furry black and white kind!) causes problems such as obsessive-compulsive behaviour, ticks and Tourette syndrome.

In this study researchers showed how a specific strain of streptococcus bacteria – GABHS – can cause PANDAS symptoms in mice.

Delaying motor neuron disease

By blocking the production of a faulty protein in mice, researchers have delayed the onset of motor neurone disease, improved mobility, and extended life-span. Motor neurone diseases affect the cells that control movement.
