Two young males in their thirties are reported with a clinical history and examination indistinguishable from typical females with the Rett syndrome. Both had normal early development. The first patient had a regression by the end of the second year. He was late in walking, had prominent hand-wringing from the age of 4 years, and non-progressive dystonia from the age of 14 years. He is still ambulatory. Seizures which started at the age of 18 months have been easily controlled. The second patient has had a severe seizure disorder since the age of 7 months. In his early teens, he lost ambulation and his height and weight fell below the 2nd percentile. He has severe foot dystonia without spasticity. Both patients have a normal head size and no evidence of atrophy on a CT scan of the brain. Both had kyphoscoliosis in their teens. It is difficult to evaluate the incidence of such cases. Little attention being paid to the normal early development, they hide behind vague diagnoses such as cerebral palsy, static encephalopathy, and behavior disorder. Dystonia is often confused with spasticity, the lack of paralysis is not appreciated, apraxia and hand wringing are assumed to be self-stimulatory behaviors.

Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease inevitably leading to generalized muscle weakness and premature death. Sleep disturbances are extremely common in patients with ALS and substantially add to the burden of disease for both patients and caregivers. Disruption of sleep can be caused by physical symptoms, such as muscle cramps, pain, reduced mobility, spasticity, mucus retention, and restless legs syndrome. In addition, depression and anxiety may lead to significant insomnia. In a small subset of patients, rapid eye movement (REM) sleep behavioral disorder may be present, reflecting neurodegeneration of central nervous system pathways which are involved in REM sleep regulation. With regard to overall prognosis, sleep-disordered breathing (SDB) and nocturnal hypoventilation (NH) are of utmost importance, particularly because NH precedes respiratory failure. Timely mechanical ventilation is one of the most significant therapeutic measures to prolong life span in ALS, and transcutaneous capnometry is superior to pulse oxymetry to detect NH early. In addition, it has been shown that in patients on home ventilatory support, survival time depends on whether normocapnia, normoxia, and elimination of apneic events during sleep can be reliably achieved. Several studies have investigated sleep patterns and clinical determinants of sleep disruption in ALS, but exact prevalence numbers are unknown. Thus, constant awareness for sleep-related symptoms is appropriate. Since no curative treatment can be offered to affected patients, sleep complaints should be thoroughly investigated in order to identify any treatable etiology and improve or stabilize quality of life as much as possible. The use of hypnotics should be confined to palliation during the terminal phase and refractory insomnia in earlier stages of the disease, taking into account that most compounds potentially aggravate SDB.
