The report
The patient receives a clear report with findings, implications, and recommendations. If you are the treating physician, we can send a copy with the patient’s consent.
For colleagues
Information for clinicians
How to refer a patient, which studies we perform, and how the report is delivered. The laboratory is built for neurology, internal medicine, cardiology, rheumatology, and pediatrics.
How to refer
- 01
A short note is enough: reason, medications, prior studies, and whether there is orthostatic hypotension, syncope, parkinsonism, or neuropathy.
- 02
Write to appointments or to clinical direction. WhatsApp also works to coordinate site and preparation.
- 03
A formal referral is not required. If you have one, it shortens the path.
Studies we perform
- Tilt-table testing with beat-to-beat monitoring and continuous cerebral blood flow (transcranial Doppler ultrasound)
- Transcranial ultrasound with a tilt-table protocol for patients with stroke of undetermined etiology (cryptogenic)
- EEG and brain mapping
- Cognitive screening
- Movement evaluation
- Evaluation of the sense of smell
- Functional bladder ultrasound
- Thermography
- Coming soon: sudomotor evaluation (Sudoscan)
- In-person or virtual visits, including pediatrics

When evaluation is indicated
We use the laboratory’s 2026 algorithm. Red is not an emergency-department alert: it means autonomic testing is indicated from the start.

What the recording looks like
Control: healthy 73-year-old adult
Report from a protocol in a healthy 73-year-old adult: blood pressure and pulse, middle-cerebral-artery transcranial Doppler, and heart-rate variability (PNS/SNS indices).
Autonomic failure: 69-year-old man
The same report in a 69-year-old man with autonomic failure. Deep-breathing heart-rate response 2.1 bpm; PNS −0.88, SNS 2.90. Santa Fe Dysautonomia Center.
Research
The laboratory documents dysautonomia and movement-disorder phenotypes in Mexican populations. Collaborations and protocols are on ResearchGate.
