Patient Q&A Section

How many people get apnea a year in the United States?

"Approximately 1.5 million adults, mostly women, have obstructive sleep apnea while about 1.3 million have central sleep apnea. This data should help to inform practitioners of the importance of screening for sleep apnea as they are at higher risk of complications from sleep apnea, including cardio- and cerebrovascular accidents, and congestive heart failure." - Anonymous Online Contributor

Unverified Answer

What causes apnea?

"apnea may be the result of several underlying organic, neurological, or psychological mechanisms, all involving some abnormal functioning or structure of the brain. The most plausible theory is that apnea arises from insufficient neuronal discharge as a normal response to an acute change in oxygen concentration." - Anonymous Online Contributor

Unverified Answer

What are common treatments for apnea?

"When the cause of respiratory arrest is known, it is reasonable to proceed immediately for tracheal intubation, and proceed to resuscitation attempts. If CPR fails, then artificial ventilation must be instituted immediately to obtain appropriate oxygenation." - Anonymous Online Contributor

Unverified Answer

What is apnea?

"All of these patients have apnea but they were not given the appropriate diagnostic evaluations for this disorder. In these patients, apnea is a disorder in which the patient was not monitored appropriately. This lack of monitoring can easily lead to the development of an apnoeic event and consequently death in the absence of appropriate treatment." - Anonymous Online Contributor

Unverified Answer

Can apnea be cured?

"There is poor evidence that adenotonsillectomy reduces the likelihood of the occurrence of apnoeic spells in children. Tonsillectomy did not alter the rates of subsequent adenoid growth when performed according to published guidelines for the surgery of children between 2 and 4 years of age." - Anonymous Online Contributor

Unverified Answer

What are the signs of apnea?

"In neonatal intensive care unit patients, apnea has been seen in infants as young as 24 hours old. In this population, apnea signs can include a decrease in respiratory rate or oxygen saturation. In contrast to infants, apnea does not occur in healthy infants, and these infants are generally free of signs of apnea." - Anonymous Online Contributor

Unverified Answer

What is the primary cause of apnea?

"Sleep-related respiratory disturbances may be primary in approximately one-third of children with sleep-related breathing disorders. The most common and predictable cause of apnea is an upper airway collapse during sleep and is not limited to the obstructive pathologies found in infants. The diagnosis of apnea in young children and treatment of apnea vary greatly from that of adults. Treatment of breathing abnormalities should therefore be taken into account in the management of each individual patient." - Anonymous Online Contributor

What are the common side effects of alpha lipoic acid 600 mg oral tablet?

"The most common side effect of ALA is headache. The headache tends to resolve after the medication is stopped, and it is thought that it results from the drug's ability to scavenge reactive oxygen species (ROS). The second most common side-effect is constipation. It is recommended that if you are taking a patient medication with ALA that you do not take more than your daily dose of 1200 mg ALA at a time." - Anonymous Online Contributor

Have there been other clinical trials involving alpha lipoic acid 600 mg oral tablet?

"The treatment of LA in patients diagnosed with T1-4N 0-1 M0 disease was well tolerated. It was shown that LA (600 mg/day) is ineffective for treatment for patients with lung-limited or head-and-neck cancer and for those who have not had successful treatment prior to the inclusion in the study. In the same study, the overall survival was prolonged by a median of 3 months. The most frequent toxicity was leukopenia, which occurred in 27 % of patients, but was generally mild. The most common site of toxicity was in the hematologic system, primarily leukopenia and thrombocytopaenia, which occurred in 14 % of patients." - Anonymous Online Contributor

What are the latest developments in alpha lipoic acid 600 mg oral tablet for therapeutic use?

"ALA 600 mg oral tablet is a well tolerated, well tolerated and effective treatment for MELAS syndrome. There is a need to determine the long term efficacy of the treatment." - Anonymous Online Contributor

Unverified Answer

Who should consider clinical trials for apnea?

"Most clinical Trialists have no information regarding the comorbidities of patients presenting to trials to be treated for [sleep apnea]( This information may influence an investigator's perception of a patient's willingness to participate in a sleep disorder treatment trial and may potentially influence clinical Trialists' decisions regarding the patients they select for inclusion in a clinical trial." - Anonymous Online Contributor

Unverified Answer

What does alpha lipoic acid 600 mg oral tablet usually treat?

"Although it is used in a broad range of conditions, including rheumatoid arthritis and osteoarthritis, this review showed no evidence for any benefit of L-α lipoic acid 600 mg for controlling the pain or improving the function, mobility, or comfort in these conditions. This review also found no evidence to support it being useful in patients with rheumatoid arthritis associated with osteoarthritis." - Anonymous Online Contributor
