Yet, most genetic links to ASD found in recent years have involved de novo mutations, which are not passed from parent to child, but instead arise spontaneously. While these mutations help explain how ASD develops in a fraction of cases, they don't help us understand why autism so often runs in families. http://medicalxpress.com/news/2013-02-scientists-inherited-autism.html Genetics Mon, 04 Feb 2013 07:31:53 EST news279185482 Researchers have defined the gene responsible for a rare developmental disorder in children. The team showed that rare variation in a gene involved in brain development causes the disorder.

In their paper published in the journal Nature, they describe how they found iPSC cells taken from Parkinson's patients over time demonstrated the same cell disruption found in neural cells taken from other deceased patient's with the disease. They also found that by introducing a compound known to disrupt the gene mutation, that they could reverse the cell malformation. http://medicalxpress.com/news/2012-10-stem-cells-neural-cell-disruption.html Parkinson's & Movement disorders Thu, 18 Oct 2012 09:40:03 EST news269768714 Family members who care for terminally ill patients at home can be helped by nurses throughout the course of the illness and particularly after the patient's death, according to Penn State nursing researchers. http://medicalxpress.com/news/2012-09-nurses-caregiver-grief.html Health Sun, 16 Sep 2012 06:55:40 EST news266997320 (HealthDay)—Some patients with congenital generalized lipodystrophy (CGL), who lack adipocytes and develop severe insulin resistance, have a defect in adipocyte development that can be partially reversed, according to a study published online Aug. 28 in Diabetes. http://medicalxpress.com/news/2012-09-congenital-disease-linked-adipocyte.html Diabetes Fri, 07 Sep 2012 13:10:01 EST news266238371 (Medical Xpress) -- In typically developing children, links between behavioral issues and disrupted sleep have been well-researched, though fewer studies have focused on understanding how early sleep disruption affects children with Down syndrome. http://medicalxpress.com/news/2012-08-disruption-toddlers-syndrome-affect-behavior.html Diseases, Conditions, Syndromes Thu, 02 Aug 2012 08:35:50 EST news263115337 (HealthDay) -- A novel cannabinoid formulation, nabiximols, is safe and effective for patients with advanced cancer and opioid-refractory pain, especially at a low-dose, according to a study published in the May issue of The Journal of Pain. http://medicalxpress.com/news/2012-06-cannabinoid-benefits-opioid-refractory-pain.html Medical research Wed, 13 Jun 2012 15:00:01 EST news258817702 Women undergoing treatment for breast cancer might fight off distressing side effects and improve psychological well-being by staying off the couch.
