• Early Stage of Dementia

As per NIA (National Institute of Aging), dementia ranges in severity. In the initial days, it will impact the patient’s daily living and slowly turn to the stage where an individual will turn dependent on others. The early stage is also known as the mild stage and may last about two years. 

Let’s have a look at several symptoms that patients may experience.

• Forgetting events or misplacing items
• Struggling with planning, like making complex financial decisions
• Having trouble finding the right words during conversations
• Getting lost in familiar places due to poor orientation
• Difficulty judging distances accurately
• Experiencing mood changes, such as depression, anxiety, or irritability

• Middle Stage of Dementia

The middle stage of dementia can be recognized as the moderate stage, which lasts for two to four years. Generally, it is the longest stage, and the symptoms are very noticeable. In this stage, patients need extra support in managing their daily activities.

Here are several symptoms that dementia patients may experience during the middle stage:

• Requiring assistance with tasks like washing and dressing
• Needing help from a caregiver for daily activities
• Struggling to recognize familiar faces
• Having trouble remembering information
• Difficulty following conversations or understanding what others are saying
• Increased disorientation, such as getting up and dressing in the middle of the night
• Growing belief in things that may not be real
• Experiencing paranoia, such as mistrusting loved ones
• Having hallucinations
• Noticeable changes in behavior, such as shouting, agitation, sleep disturbances, and repetitive actions
• Difficulty with routine tasks, such as using the toilet
• Experiencing challenges with mobility

• Last-Stage of Dementia

There is nothing to wonder about here because the last stage of dementia may require extra or full-time support from family and caregivers. Based on several factors like the individual’s age and health, the last or the final stage can last around one to two years. 

Now, it’s time to have a glance at some of the symptoms patients experience.

• Memory issues, often referred to as time-shifting, are when a person believes they are in an earlier stage of their life.
