Miriam Warcup

Co Founder (BA MSc MSc)

Miriam undertook a Master's at Kings College London in 2020 in 'Gerontology and Ageing'. It was here that she specialised in 'Dementia Prevention' for her thesis, where she learnt of the little known fact, that untreated hearing loss is the biggest risk factor for dementia that we can do something about. Miriam's thesis was later published in the journal of 'Working with Older People'.

Since then, she has been on a mission to help spread the word and to empower individuals to reduce this risk factor by taking simple steps to prioritise their hearing, not only for the benefit of their brain health, but for their physical and mental health too. 

Her background is economics and business, but her passion has always been to help others. She's long had a keen interest in helping to reduce the monumental global impacts of dementia.

What causes hearing loss?

Hearing loss can stem from problems with different parts of the auditory system, from damage to the tiny hair cells in the inner ear, to issues with the middle and outer ear, or due to conditions that affect the brain.

Hearing loss can occur at any age, for a small minority it happens at birth, whilst for the large majority it occurs in the later years. Everyone experiences a decline in hearing ability as they age as once the hair cells in the inner ear are damaged, they can’t be regenerated. Whilst some causes of hearing loss are out of our control, there are others where we can intervene.

Some of the most common causes of hearing loss are explained below.

Age related hearing loss

is known as presbycusis. Most people begin to lose some hearing from the age of 40 and by the age of 80 more significant hearing loss can often be present. The reasons for age related hearing loss are multi-faceted. Often, however, it is hard “to distinguish age-related hearing loss from hearing loss that can occur for other reasons, such as long-term exposure to noise” (NIDCD). 


Noise induced hearing loss

is the number one cause of hearing loss. It can be caused by a one-off exposure to very loud sounds like a gunshot (between 140-165 decibels) or alternatively exposure to loud sounds for extended periods of time (over 70 decibels) like heavy road traffic or listening to music too loud on your headphones. The good news is, this type of hearing loss is completely preventable. See ‘how loud is too loud’ for tips on how and when it can be prevented.


Cardiovascular risk factors

The inner ear is just like other parts of the body. It needs blood supply to get oxygen and other nutrients to stay alive. The inner ear has a network of fine blood vessels that can be damaged in the same way blood vessels that feed the brain and heart can be. Injured blood vessels in the inner ear can lead to hearing loss. Cardiovascular risk factors such as smoking, diabetes, high blood pressure and high cholesterol are therefore potential causes of hearing loss too.

Brain damage

Head / Ear injuries

Head trauma or ear injuries can cause damage to the auditory system, either due to the ear being damaged or due to changes in the auditory pathway to the brain.


Genetic factors

According to the CDC, over half of hearing loss in babies is due to genetic causes and can be caused by dominant or recessive genes. Genetic factors, however, can influence anyone’s likelihood of developing hearing loss as they age. For example, men are more likely to have hearing loss than women and people with darker skin have been found to be less likely to develop hearing loss. Many other genetic factors exist that might influence a person’s vulnerability to hearing loss.

Ear wax v2

Impacted ear wax

Earwax is often a sign of a healthy functioning ear, but for some, ear wax can build-up and cause a blockage in the ear canal that prevents sound transmission leading to temporary hearing loss. If you suspect this is the case, step away from the cotton buds as they can push the wax deeper into the ear and can cause damage to your ear canal. Instead, seek advice from an audiologist to help remove the wax through syringing or microsuction.


Ototoxic medicines

These medicines have been known to cause hearing loss, tinnitus or balance problems. According to RNID there are over 100 prescription and over the counter drugs that can cause hearing loss. The dose required to cause hearing loss, however, often needs to be very high to cause significant damage. Aminoglycoside antibiotics and platinum-based chemotherapy drugs are two of the more common ototoxic medicines that can cause hearing loss.

See Ear conditions for a more extensive list of other conditions that can lead to hearing loss.
