Smells being used to treat depression:

Our sense of smell tells us where it is safe to live, helps us find food, helps us choose the right partner and recognise our own child. “Smell has been an essential survival mechanism for humans over the course of 1.5 million years,” says Professor James Goodwin, the director of science at the Brain Health Network and the author of Supercharge Your Brain. And having a well-functioning sense of smell is really important for our mental health.

In February, a landmark study by neuroscientists from the University of Pittsburgh revealed that smelling familiar scents can help improve mood in people suffering from depression. For their study, the researchers enrolled 32 people aged 18-55 with severe depression. They were exposed to 12 smells in airtight jars along with a written clue as to the scent.

It turned out smells evoked more specific memories from their lives than word cues.

Problems with autobiographical memory are a hallmark of major depressive disorder, explains Dr Kymberly Young, the co-author of the study, which means patients focus only on negative events or interpret events in a negative light. But smell-triggered memories tend to be more clear and “real” and more effective at triggering positive events, which can interrupt negative thought patterns. “If we improve memory, we can improve problem-solving, emotion regulation and other functional problems that depressed individuals often experience.”

Many of us use lavender on our pillow to help with stress and insomnia. “Lavender is an analgesic, so it reduces pain. It is also proven to be anxiolytic, so it dissolves our anxieties,” says Prof Goodwin. These soothing properties can be just as helpful in clinical settings.

Most excitingly, aromatherapy can help patients living with dementia, says Prof Goodwin who is a big believer in the power of essential oils which can permeate the brain and produce powerful chemical changes to our mood. “Normally the cells of the blood vessels in the brain are meshed very tightly to stop substances passing through what’s called the blood brain barrier. But essential oils are very small aromatic molecules that evaporate easily into the air and can be breathed in. They enter the general circulation and pass into the brain.”

There is scientific evidence that lavender oil can reduce occurrences of aggressive behaviour in dementia. But a host of essential oils can be used for the treatment of Alzheimer’s. “In dementia patients, amyloid beta protein (amyloid plaques) accumulates between the cells and we know that 6-Gingerol (ginger) reduces amyloid accumulation. Coriander, like lavender, can be used to reduce agitation. Rosemary improves concentration. Sweet orange, sandalwood, rose and bergamot also help to dissolve anxiety. Peppermint can bolster acetylcholine, a transmitter that plays a role in memory, learning and attention.” He advises families of dementia patients to use essential oils when massaging their hands and feet, add them to a bath, or heat in an oil burner as a mood lifter.

This makes it even more insidious that Covid was designed to ruin the sense of smell.
