Non-Invasive Brain Health Diagnostics

BioStream is developing a urine-based platform that combines proteomic analysis with AI-supported interpretation to help clinicians distinguish treatable NPH from neurodegenerative conditions.

The Problem

NPH is often difficult to distinguish from dementia

Up to 10% of the 5.2 million people in the U.S. diagnosed with Alzheimer’s disease may have underlying, treatable NPH.

A complex diagnostic path

80% of NPH cases are untreated due to the complex and expensive diagnostic path.

A treatable condition can be missed

NPH symptoms can resemble Alzheimer’s disease and other neurodegenerative conditions.

The Solution

A urine test instead of a spinal tap

The planned workflow uses point-of-care collection, centralized proteomic analysis, and a clinician-facing result.

Urine collection

at the clinical point of care

Proteomic analysis

measures a proprietary biomarker panel

Clinical result

supports differential diagnosis within the clinical workflow

How It Works

Simple collection. Centralized analysis. Clinical insight.

Point-of-care urine sample collection
