One Test Can't See the Whole Night: Why a Full Sleep Lab Beats an Online Home-Test-Only Program
Mail-order home sleep tests are convenient and useful for the right patient. But an online program built around a single home test is a screening funnel, not sleep care — it can only look for one disease, can't confirm its own misses, and has nowhere to send you when the answer is more complicated. Dr. Vishal Saini explains what a sleep clinic with its own fully equipped lab does differently, and why it matters for your diagnosis and your outcome.
Correlation Is Not a Diagnosis: Reading PAT and Cardiopulmonary-Coupling Sleep Tests More Skeptically
Peripheral arterial tonometry and cardiopulmonary coupling have made home sleep testing cheap and everywhere. They're useful tools — but they measure your breathing indirectly, through your autonomic nervous system, and the confident numbers they produce invite conclusions the technology can't support. Dr. Vishal Saini explains where these devices earn their keep, where the data gets over-read, and how to confirm findings against the gold standard.
Chasing Deep Sleep: What Actually Builds More N3 — and What's Just Noise
Everyone wants more "deep sleep," and the internet is happy to sell it to you. But only a handful of things reliably increase N3 slow-wave sleep — and for people with insomnia, the highest-yield move isn't a supplement or a gadget at all. Dr. Vishal Saini separates the evidence-based levers from the wishful thinking, and gives insomnia patients a realistic plan.
Does the Gummy on Your Nightstand Actually Help You Sleep? What the Cannabinoid Evidence Really Says
CBD, THC, and CBN sleep products are a multibillion-dollar category built on a thin evidence base — and on a few biological facts that should give every insomnia patient pause. Dr. Vishal Saini walks through what cannabinoids actually do to your sleep, what the latest trials show, what to realistically expect, and the cautions that rarely make it onto the label.
Putting a Brain Wave in the Bedroom: The Promise and Pitfalls of Adding EEG to Home Sleep Tests
The next wave of home sleep apnea testing wants to read your brain, not just your breathing. That's a genuine upgrade — and a genuine source of new ways to be misled. Dr. Vishal Saini explains what EEG adds to a home sleep test, where the evidence is strong, where it's thin, and the questions clinicians and patients should ask before trusting the number on the screen.
Sleep Apnea and Testosterone: Why Treating the Wrong Problem First Can Set You Back
Many men with untreated sleep apnea are prescribed testosterone replacement therapy — but the order matters. Untreated OSA disrupts testosterone at its source, and TRT can worsen sleep apnea. Dr. Vishal Saini explains the science, the sequencing, and what men in Lansing, Traverse City, and Eaton Rapids should know.
When the Treatment Becomes the Problem: What the Latest Research Says About RLS Augmentation
Restless legs syndrome can worsen paradoxically over time on the very medications meant to treat it — a phenomenon called augmentation. Dr. Saini explains the dose escalation trap, why the entire first-line treatment paradigm has been reversed by the 2025 AASM guidelines, and what the current evidence says about getting patients off dopamine agonists safely.
She Felt Better on CPAP. Then She Didn't. Here's Why That's Clinically Important.
Many patients with obstructive sleep apnea feel significantly better on CPAP for the first few months — then the hypersomnia returns, even though the device data looks fine. This isn't a compliance failure. It's a diagnostic signal. Dr. Saini explains the CPAP honeymoon effect, why OSA can mask underlying hypersomnia disorders like narcolepsy type 2 and idiopathic hypersomnia, and what the evidence-based workup looks like when CPAP stops working.
Your Dentist Calls It Grinding. Your Brain Calls It Something Else.
Most people assume sleep bruxism is caused by stress — but the research tells a different story. Sleep bruxism is classified as a sleep movement disorder, driven by brain arousal circuitry, dopamine pathways, and genetics. Dr. Vishal Saini explains what's actually happening in the brain when you grind at night.
Before Starting Xywav or Lumryz, Ask Yourself: How Did Your Body Respond to These Other Medications?
Your prior response to baclofen, gabapentin, or benzodiazepines may reveal meaningful signals about whether Xywav or Lumryz will work for you — but the hierarchy of which drugs matter most as predictors is not what most clinicians assume. Dr. Vishal Saini explains the pharmacological reasoning.
"Benadryl Knocks Me Out Cold" — Does That Mean Pitolisant Will Work Well for You? The Science Says: Not So Fast.
If antihistamines knock you out, does that mean pitolisant will supercharge your wakefulness? The pharmacology says no — and understanding why reveals something important about how narcolepsy and IH affect the histamine system. Dr. Vishal Saini explains the science.
What Your Deep Sleep Percentage Actually Tells Us — And Why It May Predict Whether Oxybate Works for You
Your N3 slow-wave sleep percentage on a sleep study may be one of the most important biomarkers for predicting oxybate response — but the story is fundamentally different for Narcolepsy vs. Idiopathic Hypersomnia. Dr. Vishal Saini explains the emerging science and what it means for your treatment.
MWCSD Now Enrolling: Brilliance Phase III Clinical Trial for Narcolepsy
Mid-West Center for Sleep Disorders is proud to announce the launch of the Brilliance Phase III clinical trial for narcolepsy, sponsored by Alkermes. We are now actively enrolling qualified patients across our Michigan locations.
