Dementia is incredibly common, with more than 10 million new cases registered every year globally. People with this mental health condition suffer from a gradual weakening of brain functionality. This results in a host of issues, such as difficulty memorizing things, struggle with simple movements, and an inability to communicate thoughts. Certain silent signs can help doctors diagnose this condition in its initial stages. Some of these early signs are: Frequent mood shifts Abrupt mood shifts are one of the early signs of dementia. A person with the condition may go from extremely irritated to happy in a matter of minutes. Identifying such mood shifts may be hard for the patient, but those around are likely to notice them. Misplacing things Forgetfulness is another early indicator. Individuals with dementia may misplace their belongings more frequently and in unusual areas. For instance, one may place a spoon inside their wallet, a set of house keys inside a sugar bowl, or an iron inside the refrigerator. Speech and language problems While speaking, it is common for everyone to sometimes struggle to find the right words. However, people with dementia often use incorrect words, or words with a different meaning and context, in any situation.
