Restricted eating, malnourishment, and excessive weight loss can lead to changes in our brain chemistry, resulting in increased symptoms of depression and anxiety (Centre for Clinical Interventions, 2018b). These changes in brain chemistry and poor mental health outcomes skew reality.
Maternal malnutrition disrupts embryonic brain growth, resulting in altered developmental patterns that affect cognition and social emotional control, as well as causing problems with memory and learning. Many such impairments persist even after birth and are likely to carry on into adolescence (Kar et al.
Early in the study of malnutrition and the brain, the cerebellum was recognized as an area that is particularly sensitive to the effects of early malnutrition (Adlard et al.
All brain structures in the recovered women were normal in volume and similar to those of control subjects. This study suggests that structural brain abnormalities are reversible with long-term recovery.
Individuals are often irritable, apathetic, and very disengaged from life. All of their thoughts are focused around food, eating, how not to eat, exercising, and weight, and this doesn't leave room for normal thinking.
The median time to recovery from severe acute malnutrition was 15 days (95% CI 14, 15). The highest incidence of recovery was observed at 15–20 days (20.06 per 100 child days' observations) followed by 20–25 days (13.63 per 100 child days' observations).
Malnutrition can cause permanent, widespread damage to a child's growth, development and well-being.
tiredness or low energy levels. reduced ability to perform everyday tasks like showering, getting dressed or cooking. reduced muscle strength – for example, not being able to walk as far or as fast as usual. changes in mood which might cause feelings of lethargy and depression.
Vitamin B12 deficiency is one of the most common types of malnutrition, and confusion is the most common cognitive effect. Malnutrition is treated by replenishing the body with the nutrients it is lacking either through dietary changes, or in severe cases, intravenously (administered directly into the vein).
Malnutrition is associated with both structural and functional pathology of the brain. A wide range of cognitive deficits has been reported in malnourished children.
Signs and symptoms of malnutrition
a lack of interest in eating and drinking. feeling tired all the time. feeling weak. getting ill often and taking a long time to recover.
Women, infants, children and adolescents are at the highest risk of malnutrition. Optimizing nutrition early in life – including the 1000 days from conception to a child's second birthday – ensures the best possible start in life, with long-term benefits. Poverty amplifies the risk of, and risks from, malnutrition.
Finally, the heart stops. How long does this take? There's great variation in the amount of time people can survive without food, depending on age, body weight, whether they have adequate water, and whether they have other underlying health issues.
A major repercussion of malnutrition is that the brain goes into a starved state. This means that is that nutritionally, the brain is actually starving. It is missing the crucial nutrients it needs to function optimally. The brain relies on glucose, a form of carbohydrate, as its main source of fuel.
If untreated, malnutrition can lead to mental or physical disability, illness, and possibly death.
The underlying disease also needs to be treated adequately to prevent malnutrition. Children with severe malnutrition need therapy in the hospital. This includes parenteral nutrition and slow introduction of nutrients by mouth. Once their condition stabilises then they can gradually be introduced to a normal diet.
Malnutrition plays an important role in the progression of cognitive decline; early recognition and treatment of malnutrition or risk of malnutrition are important preventive measures to increase the quality of care and quality of life of patients with dementia.
Prolonged semi-starvation produced significant increases in depression, hysteria and hypochondriasis (a focus on somatic concerns) as measured by the MMPI (a test of personality) Most participants experienced periods of severe emotional distress and depression and grew increasingly irritable.
