The Vitamin Deficiency Linked to Moodiness, Lack Of Motivation And Tiredness

The vitamin may have a direct effect on the brain and has also been linked to Parkinson’s disease and dementia.

Depression can be a sign of vitamin D deficiency, research suggests.

Vitamin D deficiency is linked to a 75 percent higher risk of depression.

Symptoms of depression include moodiness, lack of motivation and tiredness.

Depression is also linked to physical symptoms such as headaches, stomach aches, dizziness and muscle pain.

The results come from a study of almost 4,000 older adults in Ireland.

They were followed up over 4 years for any depression symptoms and vitamin D levels.

The results showed that people with vitamin D deficiency were 75 percent more likely to have depression symptoms.

Vitamin D may have a direct effect on the brain and has also been linked to Parkinson’s disease and dementia.

Dr Robert Briggs, the study’s first author, said:

“This is the largest representative and most comprehensive study of depression risk and vitamin D status in older adults ever conducted in Ireland.

Our findings will provide useful information to help inform public health policy – particularly regarding the proposition of the usefulness of vitamin D treatment/supplementation for depression.”

The link between vitamin D and depression is not confined to older adults.

Another study found that vitamin D deficiency is linked to depressive symptoms and more negative thoughts in young women.

Dr Eamon Laird, study co-author, said:

“This study shows that vitamin D is associated with a health condition other than bone health.

What is surprising is the large effect on depression even after accounting for other control variables.

This is highly relevant for Ireland as our previous research has shown that one in eight older adults are deficient in the summer and one in four during the winter.

Moreover, only around 8% of older Irish adults report taking a vitamin D supplement.”

The study was published in the The Journal of Post-Acute and Long-Term Care Medicine (Briggs et al., 2018).

The Personality Trait That Is A Sign Of Poor Mental Health

This personality trait is linked to mental health problems.

Being impulsive can be a sign of poor mental health, research finds.

People who are impulsive tend to prefer a small immediate reward over a larger reward later on.

Impulsive people tend to act on their immediate thoughts and emotions without thinking about the consequences.

In other words, impulsive people want to have fun now, not later — even if waiting is more sensible.

People who are depressed, have bipolar disorder, schizophrenia or some eating disorders are more likely to be impulsive.

Psychologists can measure this type of impulsivity with a test of ‘delay discounting’.

Delay discounting is the idea that people tend to discount a reward more, the longer the delay until they receive it.

So, psychologically, $5 right now is worth more than $10 in three weeks time.

Or, as the proverb has it: a bird in the hand is worth two in the bush.

People who can delay their gratification find it easier to wait for their rewards.

However, people with schizophrenia, bipolar disorder and borderline personality disorder find it particularly hard to delay gratification.

The conclusions come from a review of 43 separate studies.

Dr Michael Amlung, the study’s first author, said:

“The revelation that delay discounting is one of these ‘trans-diagnostic’ processes will have a significant effect on the future of psychiatric diagnosis and treatment.”

Among people with mental health problems, though, anorexia was the exception.

People with anorexia tend to make excessively self-controlling decisions.

This makes sense given that anorexia is a disorder characterised by a very high level of self-control over eating behaviours.

Professor Randi McCabe, study co-author, said:

“Examining factors that cut across psychiatric disorders, such as delay discounting, helps to illuminate commonalities and distinguishing characteristics amongst disorders that then guide further research on treatment and prevention.”

The study was published in JAMA Psychiatry (Amlung et al., 2019).
