Symptoms of Alzheimers Disease

The symptoms of Alzheimers disease can be broadly categorized into three stages: early, middle, and late. Each stage is characterized by a range of cognitive and behavioral changes.

Alzheimer’s disease is a progressive neurodegenerative disorder that primarily affects memory and cognitive function. It is the most common cause of dementia, a general term for a decline in mental ability severe enough to interfere with daily life. Alzheimer’s disease typically starts slowly and worsens over time.

Early-Stage Symptoms

In the early stages, symptoms may be mild and often mistaken for normal aging.

• Memory Loss: Frequently forgetting recent events or important dates.
• Difficulty Planning or Solving Problems: Struggling to develop or follow a plan, such as a recipe or a familiar task.
• Challenges Completing Familiar Tasks: Difficulty completing daily tasks, such as managing finances or driving to a known location.
• Confusion with Time or Place: Losing track of dates, seasons, and the passage of time. Sometimes forgetting where they are or how they got there.
• Trouble Understanding Visual Images and Spatial Relationships: Difficulty reading, judging distance, and determining color or contrast, which may cause problems with driving.
• Problems with Words in Speaking or Writing: Difficulty following or joining a conversation, stopping in the middle of a conversation, or struggling with vocabulary.
• Misplacing Things and Losing the Ability to Retrace Steps: Putting things in unusual places, losing things, and being unable to go back over their steps to find them again.
• Decreased or Poor Judgment: Experiencing changes in judgment or decision-making, such as giving large amounts of money to telemarketers.
• Withdrawal from Work or Social Activities: Avoiding social activities, work projects, or hobbies they once enjoyed.
• Changes in Mood and Personality: Becoming confused, suspicious, depressed, fearful, or anxious. Easily upset when out of their comfort zone.

Middle-Stage Symptoms

As the disease progresses, symptoms become more pronounced and start to interfere more with daily life.

• Increased Memory Loss and Confusion: Significant forgetfulness of events, personal history, and even familiar faces.
• Difficulty with Language and Thought Processes: Problems with language, including trouble finding the right words, organizing thoughts, or following conversations.
• Problems with Recognizing Friends and Family: Increased difficulty recognizing close friends and family members.
• Difficulty with Complex Tasks: Trouble managing finances, organizing or planning activities, and following multi-step instructions.
• Hallucinations, Delusions, and Paranoia: Seeing or hearing things that aren’t there, or having irrational beliefs and suspicions.
• Restlessness and Agitation: Pacing, repetitive motions, or difficulty sitting still. Increased anxiety, agitation, and aggression.
• Wandering and Getting Lost: Increased tendency to wander away from home and get lost.

Late-Stage Symptoms

In the final stage, symptoms become severe and patients require full-time care.

• Severe Memory Loss: Inability to recognize family members and familiar places. Significant loss of memory and cognitive skills.
• Inability to Communicate: Loss of ability to carry on a conversation or respond to the environment. Incoherent speech or complete loss of speech.
• Dependence on Others for Care: Need help with all daily activities, including eating, dressing, bathing, and using the bathroom.
• Changes in Physical Abilities: Difficulty walking, sitting, and eventually swallowing. Loss of bowel and bladder control.
• Increased Vulnerability to Infections: Higher risk of infections, especially pneumonia.

The progression and severity of symptoms can vary widely from person to person. Early diagnosis and intervention can help manage symptoms and improve the quality of life for individuals with Alzheimer’s disease and their caregivers.
