Research subject

Experimental neuropsychiatry started in 2004 to study the mechanisms of cellular membrane transport of the amino acids’ tyrosine and tryptophan, precursors of dopamine and serotonin in schizophrenia and related neuropsychiatric disorders (bipolar disorder, autism, and ADHD), by the development and use of the fibroblast model, a cellular in vitro technique. Changes in the dopaminergic and serotonergic pathway systems may lead to impairment of cognition, behaviour, and well-being.

A long-term collaborative project has started between Örebro University and Ikaria/Greece to investigate factors related to long and healthy ageing. The aim is to study genetic, environmental and lifestyle factors that are believed to affect the brain as well as well-being and are expected to explain the underlying mechanisms of longevity and healthy ageing (Ikaria Healthy Ageing)
