Therapy services to address aphasia in MASA syndrome patients include one-on-one sessions with a clinician, group therapy, or even computer-based therapy, which is becoming more popular given its accessibility.Intellectual disabilities also contribute to the social difficulties faced by people with L1 syndrome, and can range from mild to severe depending on the persons location on the L1 syndrome spectrum. People with mild intellectual disability usually have an IQ around 50-70 (100 is the average) and are slower in all developmental areas, but they have no unusual physical characteristics and are able to blend in socially. Moderate intellectual disability characteristics include being able to maintain self-care with some support from other, travel to familiar places in the community, communicate in simple ways, and having an IQ around 35–50. Severe intellectual disability is often seen in people with X-linked hydrocephalus with stenosis of the aqueduct of Sylvius (HSAS) (on the L1 syndrome spectrum) and has several key characteristics including: the ability to understand speech but otherwise having very limited communication skills; the ability to learn daily routines and simple self-care, but need direct supervision in social settings and need family support to live in a supervised home setting. Depending on the severity of the intellectual disability, people with L1 syndrome will have varying levels of difficulty in adapting to their social environments and may need considerable support from others to complete day-to-day tasks.
A positive dose–response relationship on sleep measures was observed for doses of doxepin between 1 and 6 mg in clinical studies, whereas the incidence of adverse effects remained constant across this dose range in both young and older adults. However, the incidence of adverse effects appeared to increase with longer treatment duration. A dose of doxepin as low as 1 mg/day was found to significantly improve most of the assessed sleep measures, but unlike the 3 and 6 mg/day doses, was not able to improve wake time during sleep. This, along with greater effect sizes with the higher doses, was likely the basis for the approval of the 3 and 6 mg doses of doxepin for insomnia and not the 1 mg dose.At very low doses, doxepin has not shown discontinuation or withdrawal effects nor rebound insomnia. Sustained effectiveness without apparent tolerance was demonstrated in clinical studies of up to 12 weeks duration. This appears to be in contrast to over-the-counter antihistamines like diphenhydramine and doxylamine and all other first-generation antihistamines, which are associated with rapid development of tolerance and dependence (by day 3 or 4 of continuous dosing) and loss of hypnotic effectiveness. It is for this reason that, unlike doxepin, they are not recommended for the chronic management of insomnia and are advised for only short-term treatment (i.e., 1 week).
