Have you ever felt any sudden difficulty while thinking, like you were about to say something but you just don’t exactly remember what? Or had struggled to concentrate while doing daily tasks? Or found yourself constantly distracted while in a meeting? Or constantly felt a bit foggy during a professor’s lecture? In most of the cases it need not be something of high intensity. But what it can be is a phenomenon called ‘Brain Fog’ or in simple terms ‘clouding of consciousness’ which basically is the sluggish, cloudy feeling you get in your head when you can't focus properly.
It alone is not a clinical diagnosis, though included as a symptom in delirium but it is a common experience which includes -
- Lacking concentration,
- Poor mental clarity,
- Being forgetful,
- lacking focus,
- Having slight memory impairments,
- Being overwhelmed by mundane tasks,
- Fatigued,
- Not having the right words to say at the right time,
- Slow reaction time and thinking,
- Trouble paying attention to tasks at hand,
- Feeling less wakeful and aware then normal.
There isn’t a specific timeframe as to how long you’ll experience brain fog. It’s usually, in most of the cases temporary, but the length of time you’ll experience brain fog can definitely vary.
We can compare brain fog to the literal fog which we see during cold winter months. Everything around you looks foggy and it becomes difficult for you to see clearly what is in front of you, especially when you are driving. But we see fog only during winters, right? Have you seen any fog during the summers? But if you do have, then we can conclude that it might be something unnatural or a serious issue due to climate change or any other hazard. So what we can interpret from this is that if brain fog lasts for a couple of days, its fine, but if it lasts for months and is interfering with your quality of life then contacting a healthcare provider would be the best decision. Brain fog is common and a healthcare provider can help you find out the causes.
