Whereas arduous at work on the marketing campaign path forward of elections in November, US President Joe Biden has been filmed greater than as soon as apparently freezing and turning into seemingly oblivious to the proceedings round him.
Final weekend, at a Democrat marketing campaign fundraiser in Los Angeles, it appeared as if he turned inflexible and zoned out in entrance of the gang on the 7,100-seat Peacock Theater, earlier than being gently guided off stage by former president Barack Obama.
Lower than per week earlier, movies apparently confirmed the 81-year-old President freeze for a couple of minute earlier than his speech turned slurred throughout a Juneteenth celebration – to commemorate the ending of slavery within the US – on the White Home.

US President Joe Biden seemingly freezes throughout a Juneteenth live performance on the White Home
The 81-year-old President was stated to have frozen for a couple of minute earlier than his speech turned slurred throughout the occasion in Washington
The White Home Press Secretary Karine Jean-Pierre tore into movies she referred to as ‘low cost fakes’ that confirmed the President in a day-dreaming state. ‘Simply since you’re standing up listening to music and never dancing, that isn’t a well being situation,’ she stated.
But President Biden is just not the one senior statesman within the US to apparently present these worrying tendencies.
Republican Senator Mitch McConnell, additionally 81, prompted concern when he instantly stopped talking at his weekly information convention on Capitol Hill again in July 2023. He stood nonetheless for round a minute, staring into area, earlier than being led away by aides. He later returned, saying he was ‘nice’.
Whereas anybody can area out every now and then – it may be an indication that you’re sleep-deprived, confused or distracted, as an example – it will also be a warning signal of a well being downside.
Right here, consultants clarify which circumstances can result in freezing episodes and why.
SEIZURES
Somebody who appears to instantly day-dream and lose all consciousness of what’s going on round them – with out blacking out – could also be having an absence seizure, also called a petit mal seizure, a symptom of a kind of epilepsy.
‘One of the simplest ways to explain it’s that you’re absent for as much as a minute earlier than slowly coming again to actuality,’ says Professor Fayyaz Ahmed, a guide neurologist and honorary senior lecturer at Hull College Educating Hospitals NHS Belief.
These seizures occur when electrical indicators within the mind go awry, which might happen on account of genetics or, not often, be triggered by exertion similar to intense train however are likely to happen most incessantly in kids who typically go on to outgrow them.
‘{The electrical} exercise within the mind also can misfire on account of tissue harm attributable to trauma and scarring,’ provides Professor Ahmed.
‘For instance, after a concussion some sufferers develop absence seizures that make them seem frozen and unresponsive.
‘After the seizure is over, the individual normally feels exhausted and must relaxation.’
In keeping with Epilepsy UK, this sort of seizure can occur one after one other and ‘some folks have a whole lot of absence seizures a day’.
If you happen to suppose somebody is having one, then the charity recommends it is best to ‘gently information the individual away from any hazard [especially if they are having repeated absences], stick with them till they’re absolutely recovered and be calm and reassuring’.
If somebody has had an absence seizure, though they may not want instant medical assist on the time, they need to make an appointment to see a health care provider who can determine if any checks or a referral to a specialist are wanted.
PARKINSON’S DISEASE
This progressive dysfunction affecting the nervous system and mind may cause freezing episodes that have an effect on somebody’s mobility and speech and might also trigger them to look to briefly lose consciousness of what’s occurring round them. These episodes sometimes final from a number of seconds to a minute.
Parkinson’s is attributable to low ranges of a protein, L-DOPA, within the mind, which is required to make dopamine, a hormone which amongst different issues helps to provoke and management muscle actions and motor actions similar to standing, strolling and operating.
The low L-DOPA could also be attributable to the demise of mind cells within the a part of the mind which receives messages regarding motion and co-ordination.
Why this occurs is unclear as, whereas ageing might contribute, youthful folks can develop Parkinsons’s too.
‘If there’s a lack of L-DOPA within the mind, it’s tough to co-ordinate totally different motor actions, therefore it appears as if the individual is frozen – the same factor can occur as there’s slowing down on initiation on any motor motion,’ says Professor Ahmed.
This will have an effect on somebody’s capacity to talk, ‘the shortage of co-ordination between totally different muscle tissues concerned in speech may cause mumbling and monotonous speech,’ says Professor Ahmed.
‘Some name it speech arrest – and it tends to final a number of seconds.’
Freezing episodes are likely to recur extra incessantly as Parkinson’s progresses, says Professor Roger Barker, a guide neurologist on the College of Cambridge – one concept being that this is because of harm to areas on the base of the mind, together with a construction referred to as the pedunculopontine nucleus, thought to play a central function within the initiation and upkeep of motion.
These with superior Parkinson’s might have episodes of freezing the place they’re unable to maneuver in any respect.
‘This isn’t momentary however occurs for couple of minutes to hours and is commonly relieved by taking anti-Parkinson’s medicines,’ says Professor Ahmed.
Freezing episodes can come on so instantly that they result in folks falling over in some circumstances, provides Professor Barker.
‘For some cause we are able to’t fairly clarify, their ft get “caught” to the ground and so they can’t transfer.’
There are methods that individuals can use to beat these ‘freezes’. For instance, inserting strips of tape or paper on the ground horizontally can create visible cues to immediate folks with Parkinson’s to stroll, because it helps present a information for the place to step – i.e. they are often instructed to position their foot on every line, or step over it like an impediment.
Equally, listening to sounds with a gentle rhythm, such because the beats of a metronome, can be utilized as they’ll practise strolling to maintain in time with the music, says Professor Barker.
Precisely how these assistance is unclear, nevertheless it’s thought the bodily cues assist activate components of the mind undamaged by the Parkinson’s.
‘In some folks, dopamine medicine may help, however not generally as a result of the freeze itself isn’t attributable to low dopamine however pathology [the way the disease has developed] in different components of the mind,’ provides Professor Barker.
An alternative choice is cholinesterase inhibitors – medicine which forestall the breakdown of the acetylcholine (a chemical which sends messages between sure nerve cells). An imbalance of this chemical is regarded as a think about Parkinson’s signs.
PANIC ATTACKS
A freeze episode can turn out to be worse if somebody then begins hyperventilating, and may happen if they’re feeling anxious or are having a panic assault
Extremely anxious conditions can typically trigger folks to actually freeze of their tracks for minutes or extra.
‘The freeze response dates again deep in our evolutionary previous, as we consider animals freezing to have the ability to mix in with their environment to keep away from being hunted as prey,’ Olivia Dornan, remedy supervisor on the Priory Hospital in Barnt Inexperienced, instructed Mail+.
‘People, identical to animals, have a worry centre within the mind referred to as the amygdala, which might set off a freeze response to cease additional hurt coming to us by making us tough to identify.’
A freeze episode can turn out to be worse if somebody then begins hyperventilating, and may happen if they’re feeling anxious or are having a panic assault, as this fast respiratory means extra carbon dioxide is eradicated from the physique than is produced, which makes the blood extra alkaline than regular. This will then result in confusion and different cognitive issues, provides Ms Dornan.
‘This will additionally typically result in listening to or sight being impacted which might escalate the sensation of zoning out.’
There are methods to scale back the chance of this taking place, she says.
Cognitive behavioural remedy, a speaking remedy that may change the way in which you suppose and behave, could make you are feeling much less anxious in making an attempt conditions, says Ms Dornan.
Long run, publicity remedy – a psychological remedy the place psychologists create a protected atmosphere by which to “expose” people to the issues they worry and keep away from so as to neutralise them – will also be useful, she provides.
MINI STROKES
Individuals can seem like briefly unaware of what’s going on round them, or unable to speak, whereas having a transient ischaemic assault (TIA), also called a mini stroke.
That is attributable to a brief disruption within the blood provide to a part of the mind on account of a clot which normally dissolves or dislodges by itself.
Signs, which might additionally embody weak point or paralysis on one facet of the physique, might solely final a couple of minutes or as much as 24 hours (the signs of a full stroke against this last more).
‘Mini strokes will be related to dropping consciousness or consciousness as a result of a small piece of clot breaks off from the center or from the carotid artery within the neck, which blocks the small blood vessels within the mind earlier than breaking down and dissipating,’ says Professor Ahmed.
‘This briefly reduces the blood provide to these components of the mind and may trigger lack of speech, weak point or lack of sensation in face, arm or leg.’
In keeping with the Stroke Affiliation, a minimum of 46,000 folks a yr within the UK have a TIA for the primary time and as it may be a danger issue for having a full stroke; for those who do have any signs – nevertheless transient – you will need to get medical assist.
CIRCULATORY PROBLEMS
Zoning out for seconds or – even briefly dropping consciousness – after standing up will be on account of issues with blood circulate.
The physique has ‘management mechanisms that keep blood circulate regardless of the consequences of gravity’ to make sure blood provide to the center is preserved always, Dr Chris Pepper, a guide heart specialist at Leeds Educating Hospitals NHS Belief, instructed Mail+.
‘However typically if you stand after a interval of sitting or mendacity down, it could take a number of seconds for the physique’s reflexes to kick in, so blood stress falls and dizziness and zoning out – or typically fainting – can comply with.
‘Adolescents and the aged are most susceptible to this,’ he says.
In older folks, Dr Pepper says that is prone to relate to a slower coronary heart fee or decrease blood stress attributable to the consequences of ageing.
‘By far the most typical explanation for this taking place in kids and youngsters is what is known as a vasovagal faint,’ he provides.
‘This occurs when there’s a sudden drop in blood stress and coronary heart fee as a result of spontaneous overactivity of the vagus nerve, which sends messages that contribute to manage heartbeat.’
BLEED ON THE BRAIN
An intracranial haematoma, or assortment of blood inside the cranium, may cause sufferers to zone out instantly and is normally introduced on by a burst blood vessel
A worrying risk is {that a} sudden freeze or zone out is because of an intracranial haematoma, which is a group of blood inside the cranium. The signs on this case come on instantly however can persist for hours and even longer.
It’s normally attributable to a blood vessel that bursts within the mind however will also be attributable to a head damage due, for instance, to a automobile accident or fall.
The blood might acquire within the mind tissue or beneath the cranium, urgent on the mind. The harm to the mind tissue implies that key areas of the mind aren’t functioning effectively any extra.
Signs similar to persistent headache and slurred speech or freezing that may develop proper after the damage, or days, weeks or months later.
They are often life-threatening, so it’s essential to get pressing medical assist when you’ve got a head damage.
‘Any blood clot within the mind can result in a seizure or a freezing episode,’ says Professor Ahmed.
