Resting-state EEG reveals four subphenotypes of amyotrophic lateral sclerosis

Resting-state EEG reveals four subphenotypes of amyotrophic lateral sclerosis

A recent study showed that researchers can use resting-state electroencephalogram (EEG) measurements to identify four different distinct subtypes of amyotrophic lateral sclerosis (ALS), sometimes called Lou Gehrig’s disease, a condition that results in degraded motor neuron function. The researchers also demonstrated that these subtypes are capable of predicting clinical trajectory and outcomes.

Conditions Diagnosed with EEG

The EEG is used to detect epilepsy in patients, showing irregular brain activity that indicates seizures. However, as the test records electrical activity in the brain, other diagnoses can be made or supported with an EEG.

“Punch-drunk syndrome” and the history of contact sports and brain damage

“Punch-drunk syndrome” and the history of contact sports and brain damage

Chronic traumatic encephalopathy, or CTE, was previously known as dementia pugilistica or “punch-drunk syndrome” for its association with former boxers demonstrating declining ability, memory loss, and lack of coordination. The hallmark risk factor that separates the syndrome from other tauopathies and dementias is repeated trauma to the head, otherwise known as traumatic brain injuries, or TBIs. It’s this repeated trauma where things become an issue for contact sports.

The History of EEGs

The History of EEGs

The field of electroencephalography began with the discovery of recordable electrical potentials from animals in the late 19th century, and in the 1920s, a neuropsychiatrist from Germany, Dr. Hans Berger, recorded the first potentials from human patients and created the procedure we know as the EEG.

The Vagus Nerve: An explainer of the tenth cranial nerve and its clinical implications

Vagus nerve stimulation is a treatment that has been occasionally used to treat epilepsy, treatment-resistant depression, and even Alzheimer’s dementia. Are you familiar with this unusual treatment? Are you familiar with the vagus nerve? Though it’s not commonly known, it’s a critical part of your nervous system and has many potential clinical implications. Let’s chat about the vagus nerve and vagus nerve stimulation, but first, some background and context.

How To Remove Adhesive After An EEG

How To Remove Adhesive After An EEG

During an EEG, your scalp will be prepped with gel and adhesive applied to the electrodes so they can stay in place during the test. Medical glues can be difficult to remove, so to avoid pain and tears, here are some tips on getting the pesky goo out of your hair.
