Most children aged 8-12 years with cerebral palsy experience similar quality of life (QoL) as other children, according to a new study published in The Lancet. The study found that type and severity of impairments do not affect QoL for six categories, but specific impairments are associated with poorer QoL in four categories.

A study published in The Lancet found that gene therapy can safely alleviate symptoms of Parkinson's disease, with significant improvements seen in movement and motor scores. The treatment involves injecting genetic information directly into brain cells, eliminating the need for indwelling hardware associated with deep-brain stimulation.
Research suggests that higher doses of vitamin A do not improve health outcomes for mothers and children in areas with moderate deficiency. Lower doses, as recommended by the WHO, may be sufficient to prevent mortality. The findings urge caution against increasing standard dosing schedules without further investigation.
