All forms of anemia, including mild, moderate, and severe, are associated with an increased risk of dementia, including AD that may be correlated with changes in the integrity of White Matter and cerebral perfusion.
People with low iron levels in their blood, a condition known as anaemia, are thought to be more at risk of developing problems with thinking, communication, understanding and memory.
Anemia has also been linked to mild cognitive impairment, a form of memory loss that may progress to Alzheimer's disease. Anyone with memory problems should be tested for anemia, experts advise. Anemia is sometime caused by deficiencies of vitamin B12, low levels of which have also been linked to Alzheimer's disease.
Iron plays a crucial role in many physiological processes of the human body, but iron is continuously deposited in the brain as we age. Early studies found iron overload is directly proportional to cognitive decline in Alzheimer's disease (AD).
Brain iron deficiency is associated with disruption of neurophysiological mechanisms that, within a social context that does not provide regular stimuli, compromises motor and cognitive development (e.g., impaired motor sequencing and bi-manual coordination, poor executive function, attention, and memory).
This can impact many areas of your body, including your brain. Not only does anemia reduce your energy levels, but it can also affect the way you think and feel. Anemia, particularly the iron deficiency kind, has been linked to mental health conditions like depression and anxiety.
Iron deficiency can make the difference between making you feel at the top of the world or downright sluggish. In addition, it is blamed for poor mental health such as causing anxiety and depression in people with lower iron levels.
Alzheimer's disease. This is the most common cause of dementia.
When your body isn't getting enough oxygenation due to a lack of iron, you may find it hard to maintain focus and carry out your daily tasks. In addition, you may experience mood swings and irritability. Over time, in some cases, it may cause anxiety and depression. So, all these problems are interrelated.”
Vitamin B12 deficiency
Other symptoms of pernicious anemia include:Dementia could be a symptom of pernicious anemia, a rare condition caused by low levels of vitamin B12.
Low iron intake resulting from diet and accelerated iron loss, which occurs through bleeding or breastfeeding, are the main causes of iron deficiency. The first symptoms of iron deficiency anemia tend to be neurological resulting in brain fog and fatigue.
People age 65 and older: People over 65 are more likely to have iron-poor diets and certain chronic diseases that increase their risk of developing anemia. If they develop anemia, they may have heart conditions or weakness that makes it hard for them to get around. They may have confusion or depression.
Low iron levels can lead to #Irondeficiency which puts you at risk of a condition known as iron deficiency anaemia, where the number of healthy red blood cells in your body is reduced. Its the low iron that causes the symptoms and brain fog is common associated with anxiety and inability to cope.
Research suggests that people with anemia may develop symptoms of depression, such as low mood, low self-esteem, and loss of interest in daily activities. For example, a 2018 cross-sectional study found an association between anemia and depressive symptoms.
Among the cognitive impairments caused by iron deficiency, those referring to attention span, intelligence, and sensory perception functions are mainly cited, as well as those associated with emotions and behavior, often directly related to the presence of iron deficiency anemia.
Age. The biggest risk factor for dementia is ageing. This means as a person gets older, their risk of developing dementia increases a lot. For people aged between 65 and 69, around 2 in every 100 people have dementia.
Many people affected by dementia are concerned that they may inherit or pass on dementia. The majority of dementia is not inherited by children and grandchildren. In rarer types of dementia there may be a strong genetic link, but these are only a tiny proportion of overall cases of dementia.
Deficiency of iron is reported to cause several behavioural disturbances in children. These children are irritable, disruptive, have a short attention span and lack interest in the surroundings.
Less common symptoms of iron deficiency anaemia (that are not usually connected to pregnancy) include: headaches. hearing ringing, buzzing or hissing noises inside your head (tinnitus) food tasting strange.
Anemia is a problem of not having enough healthy red blood cells or hemoglobin to carry oxygen to the body's tissues. Hemoglobin is a protein found in red cells that carries oxygen from the lungs to all other organs in the body. Having anemia can cause tiredness, weakness and shortness of breath.
As anemia worsens, your body can experience visible physical changes — your skin could become pale, your nails brittle and cuts may take longer to stop bleeding. Other symptoms associated with anemia include: Shortness of breath. Irritability.
Your body needs iron to make hemoglobin. Hemoglobin is an iron-rich protein that gives the red color to blood. It carries oxygen from the lungs to the rest of the body. Anemia has three main causes: blood loss, lack of red blood cell production, and high rates of red blood cell destruction.
