Having a mother with motor neurone disease (MND) means you have a higher risk, as about 10-15% of MND cases are familial (inherited), but it doesn't guarantee you'll get it; you have a 50/50 chance of inheriting the specific gene mutation if one exists, but not everyone with the gene develops the disease, as other factors are involved, though you should talk to your doctor about genetic counseling.
Not everyone who has the genetic mutation will develop MND in their lifetime. Typically, the longer you live, the more likely you are to develop the condition. If you have a parent with MND with no other family history of the disease, you're at a slight increased risk of MND of about 1.4%.
Symptoms of motor neurone disease (MND)
Adults of any age can get motor neurone disease (MND), but it usually affects people over the age of 50.
The first signs of Motor Neurone Disease (MND) often involve muscle weakness, leading to stumbling, a weak grip, or difficulty lifting objects, but can also start with speech/swallowing issues (slurring, choking) or muscle twitching (fasciculations) and cramps. These symptoms are usually mild and painless initially, varying by where the motor neurons are first affected, but often include fatigue and affect limbs or speech/swallowing muscles.
Those carrying a fault in a gene leading to MND have a 50 percent (one in two) chance of passing the genetic error on to their children. However, the risk of someone carrying the faulty gene actually developing MND may be lower than 50 percent in some cases.
You receive half your genes from each biological parent and may inherit a gene mutation from one parent or both. Sometimes genes change due to issues within the DNA (mutations). This can raise your risk of having a genetic disorder. Some cause symptoms at birth, while others develop over time.
For the majority of people who have a family history of ALS, the chance of passing the genetic mutation on to their children is 1 in 2 (or 50%). This is because most causative genes are known as "dominant," meaning each parent has an equal chance of passing their gene on to the child.
There is currently nothing you can do to prevent MND.
In 1963, while a graduate student at the University of Cambridge, Hawking began experiencing early symptoms of ALS, such as muscle weakness and slurred speech. These initial manifestations rapidly progressed, leading to a diagnosis that came with a grim prognosis—2 years to live.
Most people experience the onset of symptoms after the age of 40 years and MND is most common in people aged between 50 and 70 years. Although rare, for some people there is a genetic factor and they inherit from their family an increased risk of developing MND.
Several meta-analyses have underscored the correlation between MND and stress caused by trauma, particularly head trauma. However, a clear causal relationship between the two has not been definitively established [ 28 , 29 ]. Thus far, it can be confirmed that stress significantly affects the prevalence of MND.
Researchers at Durham University also found rugby players who have suffered multiple concussions have biological differences that may make them more prone to developing MND. The MND Association acknowledges there is a "correlation" between contact sports and MND.
The terminal stage is recognised as progressive weakness and often a sudden deterioration over a few days or hours. The most common cause of death is respiratory failure, usually following upper respiratory tract infection.
The exact cause of Motor Neurone Disease (MND) is unknown, but it's believed to result from a complex mix of genetic predisposition, environmental factors (like toxins or intense exercise), and lifestyle influences, with most cases being sporadic (no known cause) and only 5-10% being familial (inherited). Researchers are exploring potential triggers such as genetic mutations (like C9orf72, SOD1), heavy metals, pesticides, viruses, and issues with cellular waste disposal or nerve signaling.
nearly always follows what is known as a 'dominant inheritance pattern'. This means that it only takes one faulty copy of the gene to cause the disease: a person with the inherited form of MND will, in most cases, have one faulty copy and one normal copy.
Some of the more common conditions that can mimic MND include:
Stephen Hawking's "last warnings" focused on humanity's existential risks, urging us to become a multi-planetary species to survive threats like climate change, asteroids, and rogue artificial intelligence (AI). He warned that unchecked AI could surpass human intelligence, potentially replacing us, and emphasized the need to colonize other planets before Earth becomes uninhabitable due to self-inflicted or natural disasters, as detailed in his posthumous book Brief Answers to the Big Questions.
Vitamin B12 deficiency can mimic ALS, particularly in its presentation of weakness, numbness, and balance problems. Both conditions can affect the nervous system and lead to muscle weakness and neurological symptoms.
ALS is a progressive neurodegenerative disease that attacks motor neurons in the brain and spinal cord. This results in the wasting away of muscle, loss of movement, and eventual paralysis. The disease is 100% fatal, with most people living 3-5 years after diagnosis.
Five significant signs your brain might be in trouble include memory loss (especially recent events), difficulty with familiar tasks or language, confusion about time/place, significant personality/behavior changes, and problems with judgment, focus, or coordinating movement, often indicating conditions like dementia, brain injury, or other neurological issues, requiring a doctor's visit.
It is known that men develop MND more frequently than women and that the disease seems to occur earlier in life in men than women, but the reasons behind this remain unclear. .

Around 90% of autism cases are attributed to genetic factors, meaning autism is highly heritable, with many different genes contributing, rather than a single cause, often interacting with environmental influences during early brain development, though specific environmental factors don't cause it but can increase risk. Twin studies show strong genetic links, with concordance rates between 60-90% in identical twins, and research points to complex interactions of many genes and prenatal/perinatal factors.
If an individual is found to have a gene mutation associated with ALS, each of that person's first-degree relatives — siblings and children — has a 50 percent chance of also carrying the gene mutation that causes familial ALS. A person who carries the gene mutation is at high risk to develop ALS.
Q: Is autism genetic from mother or father? A: Autism can be inherited from either parent, as it often involves a combination of genetic factors. No single parent is solely responsible, and it typically results from a complex interaction of genes from both sides.
