Amyotrophic lateral sclerosis (abbreviated ALS) is a form of motor neuron disease caused by the degeneration of neurons in the brain. The condition is often called Lou Gehrig’s disease in North America, after the famous New York Yankees baseball player who was diagnosed with the disease in 1939. The disorder is characterized by rapidly progressive weakness, muscle atrophy and fasciculations, spasticity, dysarthria, dysphagia, and respiratory compromise. ALS is a fatal disease with most affected patients dying of respiratory compromise and pneumonia after 2 to 3 years; although occasional individuals have a more indolent course and survive for many years. The cause is usually unknown, but a new Canadian finger length study suggests that the onset of ALS may even be determined before birth!

For patients without a family history of the disease, which includes ~95% of cases, there is no known cause for ALS – though environmental causative factors have been indentified.

Interestingly, earlier this year a new Canadian finger length study suggests that the onset of ALS may partly be established even before birth!

The Canadian researchers report:

“A biomarker that has generated considerable interest is digit ratio, the ratio of the second (index) finger to the fourth (ring) finger, 2D:4D. Men have a longer fourth digit relative to the second digit than do women, and the ratio is lower in boys and men than in girls and women. 1 A reduced 2D:4D ratio is assumed to indicate reduced prenatal androgen exposure or sensitivity and high prenatal testosterone levels.”


PEOPLE WITH A LONGER RING FINGER ARE NOT ‘AT RISK’!

NOTICE: Even if you have a longer ring finger, you are probably NOT 'at risk' for ALS!

 The researchers hasten to explain, however, that this does not mean people with long ring fingers will develop the disease — or even that they are at higher risk for it.

“We have not done a study that shows the risk of subsequently getting ALS in people with long ring fingers,” cautioned lead researcher Ammar Al-Chalabi, a professor of neurology and complex disease genetics and director of King’s MND Care and Research Center at King’s College London.

What the study does find, Al-Chalabi said, is that “people with ALS tend to have more ‘male’ hands in that the ring finger is relatively longer than the index finger – something that is a tendency in men.”

“We already know that ALS is commoner in men, but this might suggest that the reason is something to do with the balance of hormones we are exposed to in the womb, because finger length seems to be determined in part by the amount of male hormone a developing baby is exposed to,” he added.

Five things that your fingers can tell you.

Five things that your fingers can tell you.

Your five fingers relate to the Big Five of life: evolution, sports, behavior, diseases & your sex life:

John Manning is a professor at the University of Swansea and he wrote the book “The Finger Book”. Professor John Manning explains in his book how the ratio of the index finger and ring finger (= the ‘2D:4D digit ratio’ finger length) is related to the ‘Big five’ of life.

FINGERS & EVOLUTION

The human thumb is known as a ‘marker’ for the evolution of human kind; however our relative long index finger – compared to the ring finger – is a likewise example. In the chimpanzee and gorilla, this hand feature is different: they always have longer ring fingers and a short index finger.

THE RING FINGER & SPORTS

Exceptional performances in sports are being linked to the amount of male hormones that people absorb before birth while they stay in the womb. The ‘digit ratio’ has frequently been used to predict performances in various sports leagues.

THE INDEX FINGER & SOCIAL BEHAVIOR

Interestingly, especially among children a short index finger may indicate a lack of empathic ability.

CROSS-CONTAMINATION

There is growing statistical evidence that our finger ratios are a reliable predictor of our receptiveness to diseases. However, in real life the findings have not yet shown to have a significant impact.

YOUR FINGERS & YOUR SEX-LIFE

Men with long ring fingers, consider themselves as attractive. Studies show that women in the general rule agree and confirm the judgements of these men. Surprisingly, a likewise result has been found in women.
