Mental Clarity

What Causes Reduced Mental Clarity?

Reduced mental clarity can have various causes, ranging in severity from 'very minor' to 'very serious'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • check your overall health status
  • understand what's happening to your body
  • have a doctor review your case (optional)

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose reduced mental clarity, we could:

  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "reduced mental clarity" as a symptom.  Here are eight of many possibilities (more below):
  • Kali Phos Need
  • Excess Water Consumption
  • Liver Congestion
  • West Nile Virus
  • Vitamin B12 Need
  • Fluorosis
  • Allergic Tension
  • Stress

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
having a CFS diagnosis
B12 deficiency
paying poor attention to detail
depression with fatigue
major unexplained weight loss
medium-term vegan diet
specific muscle weakness
low energy/stamina
diminished perspiration
macrocytic red cells
anal itching
unsound sleep
... and more than 130 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of reduced mental clarity:
Cause Probability Status
Stress 97% Confirm
Liver Congestion 28% Unlikely
Allergic Tension 22% Unlikely
Fluorosis 2% Ruled out
West Nile Virus 1% Ruled out
Excess Water Consumption 0% Ruled out
Kali Phos Need 0% Ruled out
Vitamin B12 Need 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

In the Mind Health section of the questionnaire, The Analyst™ will ask the following question about mental clarity:
How 'clear' is your mind / thinking? A 'clear' mind comes quickly and accurately to conclusions; a 'foggy' mind has trouble doing calculations or making decisions that should normally be simple.
Possible responses:
→ My mind is always/almost always 'foggy'
→ My mind is often 'foggy'
→ Average / don't know
→ My mind is usually 'clear'
→ My mind is always/almost always 'clear'
Based on your response to this question, which may indicate poor mental clarity, reduced mental clarity, average mental clarity or good mental clarity, The Analyst™ will consider possibilities such as:
Effects of a Low Carbohydrate Diet

Experts have voiced a longstanding concern that ketosis might fog up people's thinking, but it took until 1995 to be formally tested.  As reported in the International Journal of Obesity article "Cognitive Effects of Ketogenic Weight-Reducing Diets," researchers randomized people to either a ketogenic or a nonketogenic weight loss diet.  Although both groups lost the same amount of weight, those on the ketogenic diet suffered a significant drop in cognitive performance.  After one week in ketosis, higher order mental processing and mental flexibility significantly worsened into what the researcher called a "modest neuropsychological impairment." [International Journal of Obesity 19 (1995): p.811]

Epstein-Barr Virus (EBV)

Impaired reasoning is said to be a symptom of EBV.

Excess Water Consumption

Symptoms of fluid overload include a gradual mental dulling, drowsiness, weakness, confusion, coma, convulsions (and even death!)
