Why Doesn’t Biden Blink Anymore? Medical Research Points To Early Alzheimer’s

According to doctors, most humans blink 15 to 20 times a minute.

The reason why we naturally blink is so our eyes will be cleansed and moistened.

Well, it appears Joe Biden is unable to blink anymore.

Just take a look:

Was he just trying super hard to read the teleprompter or does his lack of blinking actually point to a serious disease such as Alzheimer’s?

According to medical research blinking deficiency and bizarre stare-gazing patterns are one of the many symptoms of Alzheimer’s.

Medical research on Future Medicine revealed these details:

Oculomotor research has revealed different types of eye movement deficits, which may either early detect AD or correlate with its severity. Seminal study by Hutton et al.  reported three types of oculomotor disturbances during spontaneous visual exploration: ‘poorly regulated gaze patterns’, ‘programming type of gaze perseveration’ and ‘staring gaze pattern’. Consistently, quantitative analysis of exploratory eye movements was suggested to early detect AD-type dementia.

During fixation, higher occurrence of saccadic intrusions was suggested to be sensitive to the progression of AD. Increased blink occurrence during fixation and pursuit, eye blink conditioning deficit , eye–head and eye–hand coordination impairments have also been reported in presumed AD. The literature on pursuit eye movements (10.6%) has led to consensual findings. Pursuit in AD-type dementia has reduced gain and velocity and exhibits more catch-up saccades or saccadic intrusions, which are better defined as anticipatory saccades with higher amplitude [6]. Some pursuit indicators were reported to correlate with AD severity. Another 10.6% of literature was dedicated to saccades, with contradictory results.

Pioneer research showed increased latency (i.e., reaction time) of reflexive saccades, which was correlated  or not with dementia severity. Five studies examining reflexive prosaccades and voluntary antisaccades corroborated increased latency of the former and additionally evidenced more systematic deficit in the latter. Indeed antisaccade measures appeared to be the most specific to AD. However, eye movements have not shown any superiority to neuropsychological testing to differentiate AD from other dementias.
