  • Restricted Sleep Increases Some Symptoms of Migraine, Study Finds

    Original Article | Sleep Review

    PharmacyTimes: Using a transcranial magnetic stimulation method, researchers have found that reduced sleep alters central nervous inhibition from GABAergic and dopaminergic mechanisms differently in individuals with migraines versus those without.

    Migraine is a primary headache disorder with a well-established association with insufficient sleep. According to the study, migraine affects approximately 15% of adults aged 15 to 64 globally and is the leading cause for years lived with disability below 50 years of age. Many patients with migraine report problems with sleep, headaches upon awakening, and using sleep as a way to avoid a headache. Researchers have also found worse sleep quality compared to individuals without migraines, as well as an increased likelihood for insomnia-like sleep patterns among individuals with migraines.

    Sleep restriction with about 50% sleep for 2 nights is a human experimental model of insufficient sleep, according to researchers. In healthy subjects, sleep deprivation may alter cortical inhibitory and facilitatory systems, and seems to increase pain sensitivity. Increased sensitivity to pain has previously been discovered in patients with migraine and may be associated with both increased homeostatic sleep pressure caused by increased need for sleep as well as reduced intracortical inhibition.

    Despite these findings, both the underlying pathophysiology of the disease and its relationship with sleep are unexplained. In order to investigate this association further, researchers applied transcranial magnetic stimulation to analyze possible mechanisms of insufficient sleep in patients with migraine.

    According to the analysis, sleep restriction had an opposite effect on cortical silent period duration in interictal migraines and controls. The cortical silent period refers to an interruption of voluntary muscle contraction by stimulating the contralateral motor cortex. With sleep restriction, this period was reduced from 147.9 minutes to 139.6 minutes. This impact was still significant when replacing sleep condition with measured sleep time in minutes.

  • Philips CPAP Recall Leaves Truck Drivers with Sleep Apnea Between a Rock and a Hard Place

    If you are a truck driver, or if you have a job that mandates you treat your sleep apnea, you may want to think about having back up therapy for your OSA.  That could include a second CPAP or an alternative to CPAP, such as oral appliance therapy.  Some of our patients that use CPAP, have an oral appliance they use when they experience power outages, go camping or use for general travel when they do not want to carry their CPAP,

    Overdrive: In the wake of the Philips CPAP recall, an Oregon-based truck driver has filed a class action lawsuit due to not being able to work while not being treated for sleep apnea.

    Philips, which also manufactures light bulbs and various electronics, issued the recall on June 14. The recall was intended to address the polyester-based polyurethane (PE-PUR) sound abatement foam, which is used to reduce sound and vibration in the affected devices. The material may break down and potentially enter the device’s air pathway. A full list of affected devices can be seen here.

    This presents a critical decision for truckers with sleep apnea using affected Philips devices and their treating physicians. Such haulers can stop using the device and wait for the recall to play out to have the device repaired or replaced, or try to purchase a new device. Alternatively, they might continue using an affected device and take a chance with the potential health risks that prompted the recall. 

    Gerry Shelton, a truck driver based in Boring, Oregon, filed a class action lawsuit on June 29 against Philips seeking a refund, replacement with a non-defective device, costs for ongoing medical monitoring, and all other appropriate damages for all the injuries he has suffered as a result of his defective device.

    According to the lawsuit, Shelton was diagnosed with sleep apnea and purchased a Philips Dreamstation BiPAP machine in 2020. Because of the recall, he allegedly was forced to stop using the machine, the lawsuit states, which also forced him to stop driving a truck “because he cannot drive with untreated sleep apnea.” The lawsuit also claims Shelton went into atrial fibrillation (increased and irregular heartbeat) as a result of not using the machine.
