  • Sleep Deprivation: The amount and type of sleep are important for memory because sleeping too little or waking up frequently at night leads to fatigue that interferes with the ability to gather and retrieve information.
  • Depression: Depression can cause difficulty paying attention and concentrating, which can affect memory.
  • Stress, tension, and anxiety: Anxiety and stress can affect concentration and distract attention, which negatively affects the ability to remember, and stress caused by emotional trauma, for example, can lead to memory loss.
  • Nutritional Deficiencies: Nutrition plays an important role in the proper functioning of the brain, and the lack of certain nutrients such as vitamins B1 and B12 can negatively affect memory.
  • Head injuries: Serious head injuries resulting from a traffic accident or a fall, for example, can lead to short or long-term memory loss, and memory can gradually improve with it. the weather.
  • Stroke: A stroke occurs as a result of a blockage of blood flow to the brain due to a blockage of a blood vessel to the brain or a leak in a vessel in the brain. Strokes often cause short-term memory loss. A person with a stroke may bring back childhood memories to him, but he doesn't remember what he ate for lunch.
  • Dementia: Dementia is a progressive loss of memory and other aspects of the thinking process that can be severe enough to affect the ability to work and perform daily activities. Alzheimer's illness is a typical kind of dementia.
