Nocturnal Asthma Increases Risk Of Psychological Problems LONDON, ENGLAND -- May 21, 1998 -- Mood disorders, poor memory and poor concentration in children can be caused by sleep disruption as a result of nocturnal asthma, finds a study in the journal Archives of Disease in Childhood. Asthma is the most common chronic disease of childhood and seems to be increasing both in rate and severity. The researchers charted the sleep patterns, cognitive function and mood of 21 children with asthma and 18 healthy children aged between five and 16 over four weeks. They found that at the start of this period, the asthmatics had much higher rates of disrupted sleep and daytime sleepiness and that they performed significantly less well than the non-asthmatics on memory tests. The asthmatics also reported themselves to be more depressed, while they were rated by their parents as having significantly more learning difficulties, psychosomatic symptoms, and behavioural problems. The sleep of the children with asthma was much more disrupted by both brief and longer wakenings than that of the other children. Changes in asthma treatment significantly decreased the number and length of episodes of nocturnal waking, with a subsequent improvement in memory function and mood. "Sleep disturbance and its potential psychological effects are much more common in children with asthma than is realised and they need to be corrected as part of overall care," the authors write.
