Pik disease is a specific type of dementia that affects the frontal and temporal lobes of the brain, progresses slowly, and typically occurs between the ages of 40 and 60. It causes deterioration and damage to brain cells, which can lead to changes in thinking, speech, and behavior. Pik disease is a neurodegenerative disease characterized by the failure of nerve cells to perform their functions. This loss of brain cells initiates an irreversible process.

Although this disease is generally rare, it can occur in people up to the age of 20. Neurons in the affected areas of the brain gradually lose their ability to function, are unable to regenerate, and become unable to perform their functions. Pick's disease was first described by Arnold Pick and is therefore named after him. Pick's disease is also known as Frontotemporal Dementia (FTD) or Niemann-Pick disease, although Niemann-Pick disease generally refers to a different genetic lipid storage disease.

What are the types of peak disease?

Pik disease can occur in different types and has several subtypes:

• Type A: This is the most common type, and symptoms generally appear between 3 and 9 months of age. This type is characterized by a decline in mental and motor skills. Symptoms worsen over time.
• Type B: It usually begins in childhood, and individuals with type B peak disease usually survive into adulthood. This type follows a different course than type A.
• Type C: Unlike types A and B, type C is rare and usually inherited. This type is usually caused by a deficiency or malfunction of a specific enzyme. This condition leads to the accumulation of cholesterol and other fats in the liver, spleen, or lungs. These accumulations eventually affect the brain, causing the disease's symptoms.

Symptoms of peak disease

Symptoms of peak disease usually develop slowly and become more noticeable in later stages of the disease. Some symptoms may include:

Behavioral and emotional changes:

• Sudden mood swings
• Feeling restless, irritable, or nervous
• Inappropriate behavior or speech
• Making sudden decisions
• Lack of interest in daily activities
• Difficulty focusing
• Repetitive thoughts and behaviors
• Difficulty in social interaction
• Lack of empathy
• Not paying attention to personal hygiene and care

Oral-centered changes:

• Change in emotional eating behaviors (such as sweet consumption)
• Speech difficulties (aphasia)
• Decreased reading and writing abilities
• Word-finding difficulty
• Repeating what is said (echolalia)
• Decrease in vocabulary
• Making meaningless sounds
• Tendency to eat foreign substances

Problems with the nervous system:

• Muscle contractions (dystonia)
• Amnesia
• Difficulty in movement (apraxia)
• Weakening
• urinary incontinence
• Difficulties swallowing and eating
• Disturbances in sleep patterns
• Clumsiness and difficulty walking

What are the causes of peak disease?

Pik disease is a condition caused by the abnormal accumulation of tau protein in nerve cells. Tau protein normally serves to provide cytoskeletal and structural support for nerve cells. However, when this protein abnormally adheres to form tau protein tangles, or Pick cells, it can lead to nerve cell death.

While the causes of this abnormal accumulation are generally unknown, genetic mutations are thought to play a role. Genetic mutations, particularly related to the tau protein, can prevent the protein from performing its normal function and cause it to clump together to form abnormal structures. Over time, this can lead to the death of nerve cells, shrinkage of brain tissue, and ultimately, the onset of dementia symptoms. However, research on this topic is ongoing, and the exact causes remain unclear.

Stages of peak disease 

The stages of peak disease are classified based on the Global Deterioration Scale (GDS), which is one of the general scales used to determine the stages of dementia, although there is no specifically developed scale to determine the course of the disease.

The stages of peak disease can be determined as follows:

• Stages 1-3: In these stages, no signs of dementia are seen and cognitive decline is minimal.
• Stage 4: Moderate cognitive decline and early-stage dementia symptoms appear. It lasts an average of 2 years.
• Stage 5: Moderate cognitive decline becomes more pronounced and symptoms of mid-stage dementia increase. It lasts an average of 1.5 years.
• Stage 6: This is the severe cognitive decline stage. It lasts an average of 2.5 years.
• Stage 7: This is the most advanced stage, characterized by very severe cognitive decline and signs of severe dementia. It lasts an average of 1.5-2.5 years.

Each stage is a general scale used to assess disease progression and can vary significantly among individuals. The duration of each stage can vary from person to person, and this scale is used for general monitoring. Specifically, a specialist should determine the stage for each patient, taking into account the individual's clinical condition and symptoms.

How is peak disease diagnosed?

 While there's no specific diagnostic test for PIK, doctors make a diagnosis based on your symptoms and medical history. During the examination, specialized tests may be performed to assess memory, behavior, language, and other mental functions. These tests are typically simple pencil-and-paper tests. Sometimes, you may be asked to answer questions or draw different objects.

Your doctor may also recommend a blood test to identify the genetic factors that contribute to Pik disease. Various diagnostic and imaging tests may also be used to diagnose the disease:

• Cerebrospinal fluid tests after spinal tap (lumbar puncture)
• Computed tomography (CT) scan
• Electroencephalogram ( EEG )
• Magnetic resonance imaging (MRI)
• Positron emission tomography (PET) scan

Tests such as these are evaluated by a physician after a detailed physical and neurological examination and, together with medical history, a diagnosis is made.

How is peak disease treated?

There is no specific treatment known for Pik Disease. Treatments aim to slow the progression of the disease and alleviate symptoms. These treatments are generally used to control symptoms and can help the patient live a more comfortable life.

Medications may be used to treat some symptoms. For example, psychiatric medications may be prescribed to manage symptoms such as depression, apathy, or aggressive behavior. Additionally, stopping or changing medications that worsen confusion or are unnecessary can improve thinking and other mental functions.

In addition to treatment, supportive therapies such as physiotherapy, speech therapy, and nutritional counseling may be recommended in some cases. These therapies can help manage a patient's daily life and improve their quality of life.

The treatment plan is typically individualized, taking into account the patient's symptoms and health status. Regular checkups with a doctor are important to assess the patient's condition and determine appropriate treatment options.

Differences between Alzheimer's disease and Alzheimer's

There are important differences between Alzheimer's disease and Alzheimer's disease, but both conditions can lead to dementia. Here are some key differences between the two diseases:

• Area of ​​brain affected: Alzheimer's disease typically affects large areas of the brain, affecting many different areas. However, peak disease can affect specific brain areas, altering motor function, language abilities, and behavior.
• Age of onset: Alzheimer's disease usually begins in later life and is most common in individuals aged 65 and older, while Peak disease usually appears at a younger age, between the ages of 40 and 50. This means that symptoms appear at an earlier age than Alzheimer's.
• Symptoms: In peak disease, speech disorders, language problems, and behavioral changes are more noticeable in the early stages. In Alzheimer's disease, memory loss is usually the earliest and most noticeable symptom. In peak disease, memory loss usually occurs in the later stages of the disease.
• Hallucinations: While Alzheimer's patients may occasionally experience hallucinations or delusions, such symptoms are less common in Pik's disease.

These differences can help distinguish between the diseases. However, a proper diagnosis usually requires a detailed evaluation by a specialist doctor and certain diagnostic tests. Because the two diseases have distinct characteristics and course, expertise is essential for determining an accurate diagnosis and treatment plan.

Recommendations for people who have a loved one with PKI

• Empathy and understanding: It's important to ask loved ones how you can help and be sensitive to their needs. Try to understand their feelings and offer your support.
• Support and assistance: Consider your own abilities and limitations. Don't hesitate to ask for help when needed. You can help the patient with their daily tasks or seek professional support.
• Calm and understanding: When communicating with the patient, strive to remain calm and understanding. Avoid arguing with the patient, as this can damage trust. Try to maintain an impersonal, gentle tone and an understanding approach.
• Supporting self-confidence: Giving patients simple tasks they can do can help them maintain their self-confidence. These tasks should be appropriate to their abilities and increase their sense of accomplishment.
• Physical changes and emotional state: It is important to constantly monitor the patient's physical condition. Emotional changes can occur suddenly, so it is important to monitor the patient's physical and emotional health and provide support as needed.
• Self-care: As a caregiver, be careful not to neglect your own needs. Regular rest, participation in support groups, or seeking psychological support can also help you maintain your health.

Every individual is different, so each patient and their family member may have different needs. Seeking help from specialist doctors and support groups is crucial for better understanding and effective support.
