First diagnostic indicator for Amytrophic Lateral Sclerosis (ALS) identified

23.02.2006


Mount Sinai School of Medicine researchers have identified three proteins that may be first tools for confirming diagnosis of ALS



Claire Collier went to see her doctor shortly after she started experiencing cramping and other symptoms. This started a series of referrals and seemingly endless stream of tests. Finally, nine months later after test after test had come back negative, she received the diagnosis of ALS. Only then could she begin to receive the treatment needed to treat her symptoms.

There was not then and is not now a simple test that can tell a patient whether or not they have ALS. But a study published in this month’s issue of Neurology may change that.


Researchers from Mount Sinai School of Medicine identified three proteins that are found in significantly lower concentration in the cerebral spinal fluid of patients with ALS than in healthy individuals. These are the first biomarkers for this disease.

"ALS is a very difficult disease to diagnose. To date, there is no one test or procedure to ultimately establish the diagnosis of ALS. It is through a clinical examination and series of diagnostic tests, often ruling out other diseases," website of the ALS Association.

Giulio Pasinetti, MD, PhD, Professor of Psychiatry, Neuroscience, and Geriatrics and Adult Development, Mount Sinai School of Medicine and colleagues compared cerebral spinal fluid from patients diagnosed with ALS, patients with other neurological disorders, and healthy individuals. They found that fluid from patients with ALS had significantly lower concentrations of three proteins than either of the other groups. Evaluating the levels of these three proteins proved 95% accurate for diagnosing ALS.

The researchers found that the changes in concentration of these proteins were evident within 1.5 years of onset of symptoms. With current methods, the average time from onset of symptoms to diagnosis is two years. Testing for these protein concentrations may provide a means of early diagnosis, allowing patients to receive relief from symptoms years earlier.

"For the first time we have the possibility of developing a test that can definitively say whether or not a patient has ALS," said Dr. Pasinetti. "Such a test would eliminate the need for patients to undergo months of diagnostic evaluation and remove the uncertainty that currently lingers with physicians and patients even after a diagnosis is made."

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
