16. Confusion or mental changes

Our brain is affected by everything that happens outside and inside our bodies. 

Poor nutrition, dehydration, exhaustion, stress, genetic factors, and many others may influence brain diseases that manifest as confusion, lack of focus, and mental and behavioral changes as their main symptoms. 

Therefore, when you notice your brain is not functioning as it should, and you experience difficulties in performing simple tasks, seek professional help to address the underlying issues and begin the appropriate treatment.
