A four-line letter, signed by the attending doctor of Congress and launched by Senator Mitch McConnell on Thursday, instructed that his current spells of speechlessness have been linked to “occasional lightheadedness” maybe introduced on by his restoration from a concussion final winter or “dehydration.”

However seven neurologists, counting on what they described as unusually revealing video of Mr. McConnell freezing up in public twice lately, mentioned in interviews Thursday and Friday that the episodes captured in actual time seemingly pointed to extra severe medical issues afflicting the longtime Republican chief.

A few of the neurologists, whereas cautioning that they might not diagnose the minority chief from afar, mentioned that the letter and different feedback from Mr. McConnell’s workplace appeared to fall in need of explaining why he abruptly stopped talking throughout information conferences in late July and once more on Wednesday.

“If I gave that tape to a medical student and that was his explanation, I’d fail him,” mentioned Dr. Orrin Devinsky, a professor of neurology on the NYU Grossman College of Drugs, referring to the account given by the attending doctor of Congress on Thursday. “Medically, these episodes need to be taken seriously.”

The neurologists mentioned that the episodes justified shut medical consideration and will immediate remedy to maintain them from recurring. Whereas a number of potentialities have been instructed, together with mini-strokes, docs mentioned that the spells appeared most in keeping with focal seizures, that are electrical surges in a single area of the mind.

The senator’s aides haven’t revealed what kind of follow-up care he could also be receiving. Extra particulars in regards to the medical historical past of Mr. McConnell, 81, together with whether or not he has been having such episodes off digital camera, would additionally assist rule out different potential explanations for the spells, neurologists mentioned.

Whether or not brought on by seizures or mini-strokes or one thing else, spells like Mr. McConnell’s wouldn’t preclude most sufferers from working or socializing usually, docs mentioned.

“Seizures have a stigma in our society, and that’s unfortunate because these are very brief electrical interruptions in behavior,” mentioned Dr. Jeffrey Saver, a professor of neurology at U.C.L.A. “Between those rare episodes, which are usually well controlled with medicines, people function perfectly normally.”

Nonetheless, consultants mentioned that seizures carried some elevated threat of cognitive or behavioral issues and will have an effect on older sufferers in another way.

Hardly ever does the general public get as full a glimpse of a severe medical occasion in a public determine because it did twice in current weeks with Mr. McConnell. For neurologists, movies like these displaying Mr. McConnell from the second he appeared to lose the flexibility to talk are way over mere curiosities.

They will help kind the premise of a analysis, as do-it-yourself movies of on a regular basis sufferers sometimes do in normal neurology practices.

“They’re very helpful, because you’re not subject to the vagaries of someone’s description and you can capture the beginning of it, which is important especially for seizures,” mentioned Dr. Anthony Kim, a professor of neurology on the College of California, San Francisco.

Particulars as small because the course during which folks’s eyes are pointed throughout such an episode provide potential clues in regards to the trigger, Dr. Kim mentioned.

After watching Mr. McConnell’s signs play out — his abrupt cease in speech, his eyes mounted within the distance, his seeming restoration after about 30 seconds — Dr. Kim mentioned that “the possibility at the top of my list would be a seizure.”

That Mr. McConnell’s second spell so intently mirrored the primary pointed much more strongly to a seizure, neurologists mentioned.

Mini-strokes, which consequence from a clot that reduces blood circulation to the mind, may trigger transient intervals of impaired speech. However they not often produce the identical constellation of signs every time they recur, on condition that clots are unlikely to journey at random to the identical a part of the mind twice.

Focal seizures, however, are sometimes triggered by an irregularity in a single particular a part of the mind, creating what docs discuss with as stereotypic signs. They’re recognized to cease sufferers lifeless of their tracks, seeming to chop them off from their environment.

Sufferers can typically reply reflexively to questions throughout such an episode — as Mr. McConnell did on Wednesday, saying “yeah” when requested if he had heard a reporter’s query — even when they seem unable to voice their ideas or interact with their atmosphere.

Mr. McConnell suffered a concussion in March, a threat issue for seizures. The seizures may be brought on by a bleed within the mind or a scar from a traumatic head damage. Earlier strokes or different kinds of injury to mind tissue may result in seizures in older folks, who as a gaggle expertise the onset of seizures virtually as typically as kids do.

Some seizures are provoked by triggers like irregular blood sugar ranges. But when somebody has had two seizures that can’t be defined in that means, neurologists mentioned that might sometimes be sufficient for a analysis of epilepsy, a typical neurological dysfunction affecting greater than three million Individuals that may come up at any age. They might typically prescribe anti-seizure treatment.

“Two seizures you definitely would want to treat,” mentioned Dr. Sami Khella, the chief of neurology at Penn Presbyterian Medical Heart. “You don’t want them to happen — they’re not good for you.”

Many sufferers operate utterly usually and present regular mind wave exercise between seizures, permitting them to stay lively and dealing whilst they’re pressured to forgo actions like driving.

However they do trigger sufferers to overlook intervals of time throughout episodes. A seizure at an inopportune second, like when crossing the road, may be harmful. And focal seizures involving one area of the mind can generalize, inflicting episodes characterised by jerking actions or epileptic spasms.

Past that, one or two seizures can beget extra, a cycle that neurologists attempt to interrupt with remedy. “The more the brain seizes, the more it learns to seize,” Dr. Khella mentioned.

Different issues can comply with. A phenomenon often known as sudden, sudden dying in epilepsy kills an estimated one in 1,000 folks with epilepsy annually.

“If you do get epilepsy as an elderly individual, there are concerns about things like memory, about cognitive function, because your resilience at 80 is going to be far less than when you’re 20 or 30,” mentioned Dr. Devinsky, who directs NYU Langone’s Complete Epilepsy Heart.

Neurologists mentioned they might not rule out different potential explanations for Mr. McConnell’s episodes.

Dr. Gavin Britz, a neurosurgeon at Houston Methodist, mentioned he would wish to exclude Parkinson’s illness, which may additionally trigger freezing episodes.

However neurologists agreed that solutions that Mr. McConnell was merely lightheaded, whereas potential, have been troublesome to sq. with the video. Dehydration may exacerbate different situations, they mentioned, however such sufferers can be unlikely to remain upright or get better so rapidly with out fluids, as Mr. McConnell appeared to do.

“We don’t have 100 percent information, so we’re kind of in the dark,” Dr. Devinsky mentioned. “But we do have this very powerful clinical information, which is quite honestly how I have to diagnose seizures and epilepsy all the time, often without the video.”
