April 2018: 2 Science Headlines

1/ Social pressure

A drug is being tested which claims to help people on the autism spectrum with social skills. Balovaptan, said drug, acts on receptors. Receptors are located on the outside of cells and communicate commands to the inside of the cell. There receptors receive a hormone called vasopressin, which is a hormone from the brain which influences social behavior. Balovaptan is designed to block a receptor of a specific vasopressin, which might be linked to social anxiety says Larry Young, professor of psychiatry at Emory University. Basically, the brain sends vasopressin to cell receptors and some of these hormones affect social behaviour. This drug might be able to prevent the hormones affecting social anxiety. Behavioural “symptoms” of autism can be identified (but not limited to) as trouble in communication and interaction.

The idea of using drugs to change characteristics of people on the autism spectrum to “fit in” to a neurotypical society is worrying. That being said, it is important that such medication is available for the safety of the people that need them and for the mental well-being of the people that make the decision to take them.

We all have some form of social anxiety. Whether its tapping fingers, playing with your hair, flapping arms or other forms of stimming. People on the spectrum are under pressure to behave neurotypically to avoid bullying, rejection, discrimination – referred to as ‘masking’. This may be a solution for some but there’s a better one – it starts with ‘aware’ and ends with ‘ness’.

2/ Genes

Remember the MSSNG project which highlighted “an additional 18 gene variations linked to the development of ASD. Nature Neuroscience Journal, published a report on this project which found that the 18 newly-identified autism genes can be instrumental in understanding the pathways in the brain that affect how cells ‘talk’ to each other.” (The Biology of Autism)?

Remember the research published by Princeton University and Simons Foundation researchers where they analysed the human genome to try and predict which genes are likely to cause autism? They had linked about 2,500 genes to autism; we have an approximate total of 24,000. (Mr Autastic)

WELL: Researchers have found alterations of the gene thousand and one amino-acid kinase 2, known as TAOK2, which is so much fun to say out loud. The alterations found are thought to play a direct role in neurodevelopmental disorders, including autism.

Karun Singh, study co-author and researcher with McMaster’s Stem Cell and Cancer Research Institute said: “This is exciting because it focuses our research effort on the individual gene, saving us time and money as it will speed up the development of targeted therapeutics to this gene alone.”

img_6972Science is on its way to delivering answers to what causes autism. They are closer to finding out how to predict autism, and, as a result, closer to finding a way to prevent it. In the  meantime, it’s up to you to ask questions, to include to shatter stereotypes and to embrace the people around you.
