Sleep apnea and insomnia are the 2 mostly identified sleep issues. Once they happen collectively in the identical particular person, it’s a particular form of torment referred to as COMISA (Comorbid Insomnia and Sleep Apnea). Happily, therapy for sleep apnea and insomnia may be profitable when confirmed therapeutic steps are adopted.
COMISA impacts at the least a 3rd of individuals with insomnia or sleep apnea. Acknowledging and naming this situation is a vital step in validating a affected person’s expertise and recognizing the toll it takes, bodily, mentally, and emotionally. Profitable therapy for sleep apnea and insomnia requires this acknowledgement as the start line.
Left untreated, the results of COMISA may be debilitating and additive, with a number of signs of poor-quality sleep and impaired daytime functioning. Daytime fatigue is a standard symptom, which manifests as diminished productiveness, low endurance for each day actions, and temper swings or irritability. Relationships could change into strained below the load of sleep deprivation. Private well-being falters. These affected can really feel like they by no means actually sleep properly – and are by no means absolutely awake, both.
As a sleep drugs doctor {and professional} sleep coach, it’s my duty to assist individuals:
- get wholesome and restorative sleep night time after night time
- reliably expertise alertness and vitality within the waking hours
- regain belief of their capability to sleep and really feel awake
- get high-touch assist for the therapy of sleep issues
- be ready with instruments and assist when sleep challenges come up
All through my years of follow in therapy for sleep apnea and insomnia, sufferers grappling with COMISA have offered a singular problem. Untangling the sources of sleep disruption and implementing therapies is a tough endeavor that often takes extra experience, extra diligence, and extra time to resolve. For these studying, I hope that this data will assist you to to advocate for your self as you companion with a doctor or coach to lastly get the deep sleep you deserve.
Prognosis of Sleep Apnea and Comorbid Insomnia (COMISA)
The coexistence of sleep apnea and insomnia makes diagnosing and measuring the severity of both situation extra complicated. Insomnia and obstructive sleep apnea share threat elements (primarily weight problems and age) and a number of overlapping day/night time signs, so the likelihood that each circumstances are working throughout the similar particular person is price contemplating.
On a backdrop of stress, irregular sleep schedules, extreme caffeine consumption, environmental sleep challenges, and underlying well being circumstances (together with despair and anxiousness), there’s a lot to unpack. Sufferers with COMISA usually current with outstanding signs of sleep disruption, daytime dysfunction, and a generalized criticism of “I don’t sleep properly,” successfully lumping all results of their sleep problem collectively.
Insomnia is an instance of how the mind-body connection can go awry, and there are layers of precipitating and perpetuating elements that lead to a variety of negative effects. Roughly 6-10% of the final inhabitants suffers from power insomnia. This situation is characterised by a state of hyperarousal inflicting issues attending to sleep and staying asleep.
Hyperarousal can manifest as pondering ruminations, anxiousness, elevated coronary heart charge, and shallow respiratory. A low threshold for arousal may cause an individual to spend extra time in transitional (gentle) sleep, and this generally ends in the notion that there was no sleep in any respect.
Insomnia is a medical prognosis and severity is measured with the Insomnia Severity Index (ISI) questionnaire, which surveys each nighttime and daytime signs and yields a quantity rating meant to seize severity. For instance, a rating equal to or above 15 signifies clinically important insomnia. Penalties of untreated insomnia embrace diminished high quality of life and long-term well being dangers associated to sleep deprivation.
Sleep apnea, particularly obstructive sleep apnea (OSA), is finest characterised as a respiratory downside the place repeated airway obstructions (attributable to collapse of the higher airway throughout sleep) trigger drops in blood oxygen ranges and sleep disruption. It’s estimated that 80% of individuals with OSA haven’t but been identified. Threat elements embrace weight problems, age, airway and facial anatomy, and a few medical circumstances.
Airway obstructions can happen a whole bunch of occasions at night time for these with reasonable or extreme obstructive sleep apnea however is probably not perceived by the one with the situation. OSA is related to elevated irritation, surges within the sympathetic (battle or flight) nervous system, hormonal dysregulation, and metabolic dysfunction. With out therapy for sleep apnea, sufferers can expertise diminished life high quality and long-term results together with cardiovascular, metabolic, and neurologic illness.
Obstructive sleep apnea severity is measured with the apnea-hypopnea index (AHI), with growing AHI numbers akin to severity. The presence of untreated obstructive sleep apnea and its related signs usually elevates the ISI rating as a result of an individual with OSA can expertise related daytime signs as an individual with insomnia.
Conversely, the presence of untreated insomnia can have an effect on the AHI measurement (particularly if dwelling sleep apnea testing is used), and each insomnia and OSA are related to sleep disruption. There may be some proof that partial sleep deprivation can exacerbate OSA. This might counsel an underlying mechanism by which signs of every dysfunction predispose sufferers to the opposite.
OSA could contribute to the event or worsening of insomnia. OSA is related to transient awakenings and surges in coronary heart charge after airway obstruction. This is sensible, as a result of if an individual awakens absolutely, it’s usually tough to return to sleep and the notion could also be that of insomnia. I incessantly level out that untreated OSA is a menace to respiratory, sleep, and oxygenation, so it naturally will increase hypervigilance. Repeated situations of sleep interruption can rapidly flip into frustration which solely serves to perpetuate poor sleep and the expertise of insomnia.
After which there’s Higher Airway Resistance syndrome (UARS). This can be a situation in between benign loud night breathing and the decrease restrict of OSA, and it isn’t but absolutely understood. With UARS, elevated resistance of the higher airway (or movement limitation) is current and demonstrated with an in-lab sleep research to trigger sleep disruption. A major variety of individuals with UARS report a decrease high quality of life regardless of not having a sleep-related respiratory dysfunction acknowledged by insurance coverage standards.
In instances of UARS, the co-existence of insomnia could also be related to a diminished respiratory arousal threshold, which can predispose sufferers to awaken with smaller levels of airway narrowing. I’ve had success in my follow in treating UARS sufferers with CBT-I (Cognitive Behavioral Therapy for Insomnia) and (self-paid) modes of OSA therapy, together with PAP and oral appliance therapy.
Insomnia could exacerbate the severity of sleep sleep-disordered respiratory. Conversely, the presence of sleep apnea can contribute to the event and worsening of insomnia. COMISA impacts the prognosis and dedication of severity for each circumstances. Extra importantly, the intricate dance between insomnia and sleep apnea necessitates a personalised, holistic, and responsive method to therapy.
Remedy for Sleep Apnea and Comorbid Insomnia (COMISA)
Many sleep drugs specialists elect to start out with therapy for sleep apnea first after which decide if insomnia signs are left over. In my expertise, this can lead to a dramatic worsening of the affected person’s situation. Folks with COMISA rightly understand that their sleep is fragile and including OSA remedy to untreated insomnia ends in additional decline of sleep high quality and considerably larger impairment of daytime functioning. This usually leaves an individual feeling extremely discouraged about their capability to have wholesome sleep. So discouraged, in reality, that they could abandon care altogether.
In the midst of a sleep apnea analysis, there is a chance to deal with insomnia first. Insomnia therapy can begin whereas a affected person is ready for his or her sleep take a look at or ready for his or her OSA therapy. The primary-line therapy for insomnia is CBT-I (Cognitive Behavioral Therapy for Insomnia). This can be delivered by appropriately educated clinicians or sleep coaches. Common interactions in as little as 4-6 weeks may be extremely efficient.
First-line therapy for sleep apnea (reasonable to extreme) is with Constructive Airway Strain (PAP, comparable to CPAP, AutoPAP, and different PAP modalities), which requires acclimation to the masks and stress with nightly use for decision of OSA. You will need to notice that preliminary CPAP acceptance and use predicts future CPAP use, particularly throughout the first month of CPAP.
In different phrases, a optimistic preliminary expertise with CPAP remedy encourages and maintains larger long-term adherence. Nevertheless, for individuals who didn’t have a superb expertise with CPAP however are nonetheless motivated to deal with their sleep apnea, I’ve discovered that efficient use of CPAP can completely be achieved within the therapy for sleep apnea by teaching, assist, and schooling.
These with COMISA are sometimes much less accepting of PAP remedy (even in comparison with individuals with OSA alone), which may understandably set off hypervigilance — a barrier to acclimation to the masks and air stress. Quick-term use of prescription sleep aids, way of life modifications (together with energetic stress discount), and behaviors to interact the parasympathetic (relaxation and digest) nervous system may be customized to advertise acclimation to CPAP whereas nonetheless supporting sleep high quality and amount.
This requires belief, good communication, and frequent follow-up between the particular person with COMISA and their clinician or coach. Given the shortage of entry to sleep drugs suppliers, this work could fall to a sleep coach for a high-touch and customized plan.
Non-CPAP therapies can and needs to be thought-about within the COMISA inhabitants. Non-surgical therapies (particularly oral equipment remedy, or OAT) and surgical procedures for OSA are choices. Number of a CPAP therapy different depends on affected person choice, the severity of OSA, co-existing medical circumstances, and value or insurance coverage protection. It’s my follow to warning COMISA sufferers about hypoglossal nerve stimulation surgery as a result of the implant for OSA can exacerbate insomnia.
For extra steerage, watch my video interview about sleep apnea therapy options with out CPAP:
Sleep apnea therapy with out CPAP with Audrey Wells MD
There may be precedent for hope within the therapy for sleep apnea and insomnia. Analysis reveals that these receiving each efficient CBT-I and CPAP remedy report considerably larger enchancment of worldwide insomnia signs and significant sleep apnea therapy by 6 months follow-up.
In abstract, individuals with COMISA require a better stage of experience, extra frequent care, and focused diagnostic and remedy issues. Insomnia remedy ought to happen at the least concurrently (or ideally earlier than!) a sleep apnea analysis. Insomnia shouldn’t be assumed to be a ‘secondary’ manifestation of OSA.
Left unaddressed, underlying insomnia can considerably impair an individual’s capability to perform as they start therapy for sleep apnea, and a savvy clinician will pivot accordingly. Flexibility in selections for OSA remedy needs to be the norm, and frequent and customized follow-up visits could be best for assist and troubleshooting.
