About the symptom

Forgetfulness is described as a memory lapse or inability to retrieve stored information in the brain.

When to see a doctor

Seek professional care if you experience any of the following symptoms

  • Poor memory

Possible causes

  • Sleep disorder

    Sleep disorders are conditions that affect the quality, timing, or duration of your sleep, impacting your ability to function when you're awake. There are many types of sleep disorders, including disturbances in sleep quality or quantity, excessive daytime sleepiness, abnormal behaviors during sleep, sleep disorders related to mental disorders, and more.

  • Alzheimer dementia (AD)

    Alzheimer's disease is the most common cause of dementia. The brain shrinks, affecting memory and behavior. Symptoms worsen over time and can interfere with daily life. Increasing age raises the risk for Alzheimer dementia.

  • Mild cognitive impairment (MCI)

    Also known as mild or "pre-dementia". Patients experience forgetfulness that slightly interferes with their daily activities. Controllable risk factors include alcohol, lack of exercise, and lack of mental stimulation.

  • Progressive subcortical vascular encephalopathy
  • Adjustment disorder
  • Fibromyalgia
  • Depression
  • Dissociative disorder
  • Frontotemporal dementia

Related serious diseases

  • Cerebral infarction

    Cerebral infarction refers to damage to brain tissue resulting from a stroke. It occurs due to decreased blood supply and oxygen delivery to the brain, causing brain cell death and brain damage. It is typically caused by a blood clot or fatty/cholesterol plaques blocking a blood vessel to the brain, but can also occur if a blood vessel ruptures and bleeds into the brain.
