如何在TradingView上使用成交量分布圖(Volume Profile)?

 

(一)定義


成交量分布圖是TradingView的高級圖表研究,顯示了指定的時間段內指定的價格水平的交易活動。這個研究(允許用戶定義的參數,例如行數和時間段)是在圖表上繪製直方圖,旨在顯示基於成交量的主要的和/或重要的價格水平。從本質上說,成交量分布圖會獲取指定時間段內以特定價格水平交易的總交易量,並將總交易量分為買入交易量或賣出交易量,然後以易於理解的方式顯示出來,讓交易者可以輕鬆地查看。

(二)典型的重要水平


控制點(POC):成交量最高時段的價格水平。

分布圖高點:在指定時段內達到的最高價格水平。

分布圖低點:在指定時段內達到的最低價格水平。

價格區域(VA):價格水平範圍,在這段時間內,總成交量的一個特定百分比。通常情況下,此百分比被設定為70%,也可以由交易者自己決定。

高值區域(VAH):價格區域內的最高價格水平。

低值區域(VAL):價格區域內的最低價格水平。

(三)計算方式


如何計算價格區域(VA)

1.確定分布圖中的總成交量(總買入和賣出)。

2.將買賣總數乘以0.7,確定買賣總額的70%是多少。(70%只是一個典型範例,交易者可以選擇任何百分比)。

3.從POC開始(分布圖中具有最大總成交量的一行)並記錄其總成交量。POC將是被增加到價格區域的第一個分布行。

4.現在查看POC(初始價格區域)上方的兩行,並將兩者的總成交量相加。

5.現在查看POC(初始價格區域)下方的兩行,並將兩者的總成交量相加。

6.確定哪個總成交量較大,並將其增加到步驟3中的POC的總成交量中。

7.重複步驟4和5,將這兩個數字中較大的一個增加到價格區域中。

8.一旦用戶的價格區域的總成交量相當或略超過步驟2中的水平,則確定價格區域。

9.價格區域內的最高值的一行將是你的高值區域(VAH),而價格區域中的最低值的一行將是你的低值區域(VAL)。

根據圖表的時間周期,可以將各種周期的數據用於 成交量分布 (Volume Profile) 的計算。在計算 固定範圍 (Fixed Range) 和 可見範圍 (Visible Range) 時,我們交替嘗試使用1、3、5、15、30、60、240、1D的周期,直到計算VP的時間間隔內的K線數量小於5000。對於 時段成交量 (Session Volume),採用以下對圖表周期的對應關係:

(四)成交量分布圖功能


1、支撐和阻力位


大多數交易者首先要用成交量分布圖來確定基本的支撐和阻力位。需要注意的是,使用成交量分布圖來鑒別支撐和阻力位是一種被動方法。這意味著,與基於當前價格行為和分析來預測未來價格變動的主動方法(例如趨勢線和移動平均線)不同,被動方法依賴於過去的價格變動和成交量行為。

在市場已經觸及過的價格水平上,被動方法在應用上或意義上是有用的。基本技術分析表明,支撐位是將支撐下跌價格的價格水平,阻力位是將抵抗上漲價格的價格水平。因此,可以得出這樣的結論:即在分布圖底部附近的價格水平在數量上極度有利於買方,這很好地表明了支撐位。反之亦然。分布圖頂部附近的價格水平非常有利於賣方交易量,這很好地表明了阻力位。

2、成交量節點


高成交量節點(HVN)是價格水平或附近的交易量峰值。HVN可以視為鞏固期的指標。通常,買賣雙方都有大量活動,與成交量分布圖中的其他水平相比,市場在該價格水平上停留了很多時間。這可能意味著資產的“公平價格區域 (fair value area)”。當價格接近先前的HVN(或公平價格區域)時,將持續一段橫向波動。市場不太可能立即突破該價格。

低成交量節點(LVN)則相反。它們是價格水平或附近的最低谷(或大幅下降)。低成交量節點通常是突圍反彈或崩潰的結果。在反彈或崩潰期間,通常會出現最初的交易量暴增,然後大幅下降。下降可能意味著資產的 “不公平價格區域 (unfair value area)”。

當價格接近先前的LVN(或不公平價格區域)時,市場更有可能反彈至該價格水平或從該價格水平反彈。由於它被視為不公平的價格區域,因此與成交量分布圖中的其他某些價格水平相比,市場價格在該處流連的時間不會太久。

(五) 案例策略


和大多數其他工具或研究一樣,成交量分布圖有許多用途。有許多交易策略,將成交量分布圖作為重要組成部分。下面是一個使用該工具的策略,該策略基於將當天的開盤價與前一天的交易量分布進行比較。

l.如果當日開盤價高於前一交易日的價格區域(但仍低於成交量分布高點),則價格將回撤至控制點,然後繼續上漲(開盤方向)。因此,在撤回控制點期間,存在買入機會。

2.如果當天開盤價低於前一交易日的價格區域(但仍位於成交量分布低點上方),則尋找價格以回撤至控制點,然後繼續下跌(開盤方向)。因此,在撤回控制點期間,存在賣出機會。

3.如果當天的開盤價完全超出了前一天的成交量分布(高於成交量分布高點或低於成交量分布低點),則可以認為,這是相對於前一天的成交量分布範圍而言開盤價的方向的一個可能的繼續前進。

(六)總結


交易量分布圖是一種非常有價值的技術分析工具,各地的交易員都在使用。交易量分布圖持續相關性的關鍵在於其多功能性。它是一種圖表工具,確實具有廣泛的用途。與許多其他研究不同,關於交易量分布圖的實用性幾乎沒有爭議。交易量分布圖提供的數據是無可爭辯的,將其留給交易者以尋找新的創造性方法來使用它。儘管以最簡單的形式,它是發現傳統支撐和阻力區域的一種很好的被動方法,交易者仍在想辦法以預測性或主動性方式繪製指標。

考慮本文前面給出的交易策略範例。能夠將即時事件(當天開盤)與歷史事件(前一天的成交量分布)進行比較,並根據這種關係做出交易決策就是一個很好的例子。

High Probability Trading Strategies: Entry to Exit Tactics for the Forex, Futures, and Stock Markets Hardcover – Oct. 20 2008

 In High Probability Trading Strategies, author and well-known trading educator Robert Miner skillfully outlines every aspect of a practical trading plan–from entry to exit–that he has developed over the course of his distinguished twenty-plus-year career. The result is a complete approach to trading that will allow you to trade confidently in a variety of markets and time frames. Written with the serious trader in mind, this reliable resource details a proven approach to analyzing market behavior, identifying profitable trade setups, and executing and managing trades–from entry to exit.

Ideas found | Tradingview.com vs LuxAlgo | https://www.reddit.com/

Ideas found to work on: 

  1. Tradingview.com internal EMA crossover
  2. Jim Brown's books
  3. free indicators from Jim Brown's books
  4. Robert C. Miner's High Probably Trading Strategies
  5. Zeiierman or EzAlgo
  6. Bad behaviors: YOU YOURSELF HAVE TO BE A GOOD TRADER. People skip out on essentials like reframing your mind, controlling your emotions, and back testing.. AND THINK THEY CAN TRY TO MAKE MONEY OFF THE STOCK MARKET. 


It's hot trash, I tried their backtesting script and even with a 60% win rate, you will lose money. They are so hopeless they have an inverse setting in their indicators where you buy on the sell signal and sell on the buy signal. Pure gambling. Any pre-build strategy built in Tradingview like ema crossover has a more consistent win rate and profit percentage.

They make lots of other free indicators that may be more useful. Chances are the logic of this indicator can be found for free from a developer trying to get started and creating the scripts so they can practice their coding. Indicator companies are in the business of creating indicators of course. They will make what sells and what customers want regardless if they ‘work’. Beer companies make advertising that make it seem like beer drinkers are always having a good time but there are also bad times as well.

If you are not yet profitable then paying for an indicator will generally not change that. If you understand the logic of the indicator then you can take trades on that. The indicator only reaffirms what you already know.

I've tried them and found them to be as inconsistent as any other indicator. Just because they have far more users than some of the other paid indicators, like Zeiierman or EzAlgo, doesn't mean they're better. It just means there are more desperate people trying to find an easier way. I continue to have more luck with the methods and free indicators from Jim Brown's books and Robert C. Miner's High Probably Trading Strategies than I did with any paid scam.

Unfortunately I purchased Zeiierman indicators and they are a crap. I mean, you can do the same trades using the common set of indicators included in Tradingview. They only sell indicators with a lot of paraphernalia (colors, many many settings, alerts and so on) but they explain their use in a blurred way without any solid strategy. It is the perfect subscription to burn money.

I have the Luxe Algo ultimate plan with the back testing. I have found with extensive back testing the profitability of this indicator shoots way up when you switch from normal candles to heiken ashi candles. I have with checked in the documentationand the software supports Heiken ashi candles, although when you try to backtest on trading view it gives a warning that, it might not be accurate due to using heiken ashi. Just ignore that It does not seem to make much of a difference in the signals, whether you have normal candles or heiken ashi on, but your profitability goes WAY UP. The main indicator that seems to make the most money is actually the matrix oscillator! Use that for your entries and Signals / overlays with heiken ashi just to montor uour trades. In the oscillator turn off money flow, turn on hyper wave, set it to its fastest settings, which would be 2 and SMA on 2 well. Back testing on the 1m charts with a $10,000 capital it made 64% ($6400) u could basically automate this trading and sit back and enjoy profits. It’s a valuable indicator. You just really need to look deeply into it and back test your strategies. Other profitable indicators include just using signals overlays, just the signals only on the 5 and 10m charts. I have successfuly did a trade today live on the 10m (just paper trade) it was $1400 in about 1 hour then it gave the exit signal. Pretty good software is completely worth it but you need to backtest first because thats the only way to know you have the right settings

I use price action concepts by lux algo and found it very useful. People who think LuxAlgo is total bs are idiots. LuxAlgo is a TOOL. YOU YOURSELF HAVE TO BE A GOOD TRADER. People skip out on essentials like reframing your mind, controlling your emotions, and back testing.. AND THINK THEY CAN TRY TO MAKE MONEY OFF THE STOCK MARKET. If you try to be a plumber with no plumbing experience, are you going to blame your wrench for not doing the work? Set it up properly and take trades alongside other indicators that you have (VWAP, EMA, Pivot Points etc). LuxAlgo price action concepts, AMAZING TOOL.

Inaccurate signals. LuxAlgo causes big trading losses. 

From my experience with LuxAlgo, I would advise caution if you're considering this trading tool. I've encountered multiple issues that make it difficult to recommend. For starters, the tool often malfunctions, delivering inaccurate trading signals, which could potentially lead to significant losses. Moreover, there are ongoing technical issues, such as disappearing indicators, that require constant back-and-forth with their support team, who, despite my efforts, were unable to resolve the problems effectively.

Additionally, my attempts to get a refund due to these ongoing LuxAlgo issues were fruitless, adding to my overall dissatisfaction. The company's policy on refunds seems inflexible, even when their product fails to perform as promised. Given these serious LuxAlgo concerns about the tool's reliability and the quality of customer service, I suggest looking into more reliable alternatives in the market.

Favorite indicator | Julia's favorite | Tradingview.com | Built-in indicator | Technical Ratings

Here is the link.

Definition

Technical Ratings is a technical analysis tool that combines the ratings of several technical indicators to make it easier for traders and investors to find profitable trades.

Calculations

These are the criteria used to determine the rating of the individual indicators used. Note that changes from the last bar are used to determine falling or rising states:

All Moving Averages
  • Buy — MA value < price
  • Sell — MA value > price
  • Neutral — MA value = price
Ichimoku Cloud
  • Buy — base line < price and conversion line crosses price from below and lead line 1 > price and lead line 1 > lead line 2
  • Sell — base line > price and conversion line crosses price from above and lead line 1 < price and lead line 1 < lead line 2
  • Neutral — neither Buy nor Sell
Relative Strength Index
  • Buy — indicator < 30 and rising
  • Sell — indicator > 70 and falling
  • Neutral — neither Buy nor Sell
Stochastic
  • Buy — main line < 20 and main line crosses over the signal line
  • Sell — main line > 80 and main line crosses under the signal line
  • Neutral — neither Buy nor Sell
Commodity Channel Index
  • Buy — indicator < -100 and rising
  • Sell — indicator > 100 and falling
  • Neutral — neither Buy nor Sell
Average Directional Index
  • Buy — indicator > 20 and +DI line crosses over -DI line
  • Sell — indicator > 20 and +DI line crosses under -DI line
  • Neutral — neither Buy nor Sell
Awesome Oscillator
  • Buy — saucer and values are greater than 0, or cross over the zero line
  • Sell — saucer and values are lower than 0, or cross under the zero line
  • Neutral — neither Buy nor Sell
Momentum
  • Buy — indicator values are rising
  • Sell — indicator values are falling
  • Neutral — neither Buy nor Sell
MACD
  • Buy — main line values > signal line values
  • Sell — main line values < signal line values
  • Neutral — neither Buy nor Sell
Stochastic RSI
  • Buy — downtrend and K and D lines < 20 and K line crosses over D line
  • Sell — uptrend and K and D lines > 80 and K line crosses under D line
  • Neutral — neither Buy nor Sell
Williams Percent Range
  • Buy — indicator < lower band and rising
  • Sell — indicator > upper band and falling
  • Neutral — neither Buy nor Sell
Bulls and Bears Power
  • Buy — uptrend and BearPower < zero and BearPower is rising
  • Sell — downtrend and BullPower > zero and BullPower is falling
  • Neutral — neither Buy nor Sell
Ultimate Oscillator
  • Buy — UO > 70
  • Sell — UO < 30
  • Neutral — neither Buy nor Sell

The numerical value of the Sell rating is -1, Neutral is 0 and Buy is 1. The group and overall ratings are calculated as the average of the ratings of the individual indicators.

Recommendations for the group or overall ratings are based on this numerical rating value and determined according to the following criteria:

  • [-1.0 ≥ value < -0.5] — Strong Sell
  • [-0.5 ≥ value < -0.1] — Sell
  • [-0.1 ≥ value ≤ 0.1] — Neutral
  • [0.1 > value ≤ 0.5] — Buy
  • [0.5 > value ≤ 1.0] — Strong Buy

The basics

The recommendations given by the indicator are based on the ratings calculated for the various indicators included in it.

The overall rating of the indicator includes two large groups of indicators. The first consists of SMAs and EMAs with different lengths (MA lengths are 10, 20, 30, 50, 100 and 200), the Ichimoku Cloud (9, 26, 52), VWMA (20) and HullMA (9). The second one is calculated on the following oscillators: RSI (14), Stochastic (14, 3, 3), CCI (20), ADX (14, 14), AO, Momentum (10), MACD (12, 26, 9), Stochastic RSI (3, 3, 14, 14), Williams %R (14), Bulls and Bears Power and UO (7,14,28). Each group's rating is calculated separately, so you can select the group in the indicator settings and its respective rating calculation will be displayed on the chart.

What to look for

The Technical Ratings tool is designed to have values that fluctuate above and below a zero line. Its values are plotted as a histogram of red, blue and gray bars, and depend on your selection in the Rating is based on field of the script's inputs, where you can choose to view the value of the MAs rating, the oscillators rating, or the average of both.

Columns are gray when the value of the indicator is between 0.1 and -0.1. Progressively more saturated blue columns indicate rising values above 0.1, and more saturated red columns indicate progressively falling values below -0.1.

The label at the end of the histogram displays the state of the MAs, oscillators, and the overall rating. Its color is determined by the value of the rating selected in the Rating is based on field: gray for neutral, blue for Buy or Strong Buy, red for Sell or Strong Sell.

Summary

Technical Ratings can be a valuable technical analysis tool for many analysts or traders. Many traders use a selection of complementary indicators to make better decisions. Technical Ratings simplifies this task by combining the most popular indicators and their signals.

警惕脑梗死 | 动脉粥样硬化 | 短暂性脑缺血 | 腹型肥胖

 在我们国家,每12秒新增一名脑卒中患者,每21秒有一名患者因此死亡,脑卒中成为第一大致残和致死性的疾病,被称为第一杀手。什么是脑梗死?  

平日里大家经常听说某人“中风”了,实际上就是得了脑卒中。脑卒中包括两部分,一种是血管破裂,称为脑出血;一种是血管堵塞,称为脑梗死。  

中国每年有250万新发的脑卒中,每年有160万人是死于脑卒中,它的死亡风险比冠心病还要大三倍。  

为什么会得脑梗死?  

导致脑梗死最主要的原因,是动脉粥样硬化。正常人的血管壁非常光滑,血管粗细也均匀一致。但当一个人有动脉粥样硬化时,他首先是血管内就会形成动脉粥样硬化斑块,斑块不断长大,使得血管不断变窄,最后血管腔完全堵塞,导致脑组织死亡,我们就称之为脑梗死。  

许多人认为动脉粥样硬化可能是一个老年的疾病,年轻人可能没有问题,但实际上,它是一种伴随人一生的过程。  

人从十岁开始就启动动脉粥样硬化这个过程,但是在30岁之前,通常只是沉积,也就是说他的管壁变厚,或者开始有很薄的斑块形成,直到40岁之后,他的血管才可能发病,如果在心脏,就是心梗;在脑血管,就是脑梗。  

如何及早发现脑梗死?  

一个人如何发现自己是否得脑梗死了呢?有三种方法,第一发现有面瘫,去照镜子,会发现有一侧嘴角往下耷拉。第二发现有偏瘫,把两手平伸,一侧的肢体可能就会往下掉。第三是发现语言出现功能障碍,一个人出现言语不清楚或别人说话他理解不了的情况。遇到这三种情况,就应该马上打120或999,通过积极的溶栓治疗,降低死亡率,这时候千万不要在家休息。好多老人因为晚上发病,不想麻烦子女,结果把最好的治疗时间耽误了。  

特别提醒:  

短暂性脑缺血发作要重视:  

有些病人出现一侧肢体无力或语言障碍的症状,但过一分钟就好了,完全恢复正常。这种情况称之为短暂性脑缺血发作,是脑梗死发生的一个重要先兆。但这种情况很容易被忽视,脑梗死的病人大概有一半或者一半多在短暂性的脑缺血发作的时候没注意,等完全偏瘫了这时候才来医院,错失治疗机会。  

出现短暂性脑缺血发作的病人,24小时内20个人里面有一个人就会出现脑梗死,脑梗死发生率大概是在5%。如果是7天内,大概有8%至12%的患者他可以变成脑梗死。在三个月内,大概有20%的患者会变成脑梗死。因此,对这种短暂性脑缺血发作一定要重视。  

预防脑梗死应从源头做起:  

第一,戒烟。戒烟不光是指不要主动吸烟,同时还要求不要被动吸烟。  

第二,控制体重。正常人的身体指数应该小于24,如果在24到30之间叫超重,如果超过30,就属于肥胖。  

第三,合理饮食。每天要至少吃五种以上的水果或者蔬菜,并且控制盐的摄入量,一天吃盐量不超过6克。  

第四,每天应该尽可能保证30分钟的运动锻炼,让身体瘦下来,这样血压、血糖、血脂控制起来都相对比较容易。  

第五,管住嘴。多吃蔬菜和谷类。蛋、奶、肉、鱼要适量吃。油、糖、盐要尽量少吃。  

第六,迈开腿,多运动。快走或者是跳健身舞、游泳,都是很好的生活方式。  

第七,控制疾病危险因素。控制高血压、心脏病、糖尿病,积极治疗血脂代谢的异常。  

常见的四点认识误区:  

第一,认为脑梗死是不可预防的。实际上只要控制好,80%的患者他可能不会发展成脑梗或者心梗。  

第二,认为脑梗死不需要治疗,因为它治不好。但实际上发生脑梗死以后,如果赶快进行溶栓治疗,就可能不会遗留非常重的功能障碍。  

第三,认为脑梗死只是老年人特有的病,年轻人没有,但实际上脑梗死在各年龄段都可能发生。  

第四,认为得脑梗死后治疗六个月就会好。但是实际上得脑梗死以后,由于脑细胞的死亡是不可逆的,导致它终身无法恢复,只能通过康复把残疾降到最小。  

患脑梗死的十大危险因素:  

脑梗死的危险因素包括两大类,一类是疾病危险因素,一类是行为危险因素。把以下十项控制好,90%的危险因素就基本控制住了。  

疾病危险因素有四项:第一是高血压,它的人群比达30.6%;第二是血脂异常,占近25%;第三是心脏问题,占到近7%;第四就是糖尿病,占5%。  

行为危险因素有六项:第一是活动减少;二位是腹型肥胖,就是肚子很大,但胳膊腿并不是很粗;第三是吸烟;第四是不健康的饮食;第五是心理因素,比如焦虑抑郁。第六是酗酒。

脑梗患者越来越多,引发脑梗的6大原因,你知道吗?

 脑梗全称为脑梗塞,现代医学中也常被称为缺血性脑卒中,主要是由于脑部血液供应障碍,缺血、缺氧所导致的局限性脑组织的缺血性坏死或软化。脑血栓形成、腔隙性梗死和脑栓塞是脑梗塞临床常见的类型。据相关数据显示,脑梗塞占全部脑卒中的80%,其危害性不言而喻。

脑梗塞的危害有哪些?

大脑是指挥全身的司令官,因此大脑哪一个部位出了问题,就会导致身体相应部分的功能出现下降。

如果脑梗塞影响到言语功能,那么患者可能会出现言语不流利,讲话不清楚,词不达意等情况;

如果影响到吞咽功能,患者可能就会出现容易呛咳,饮水有呛咳、吞咽堵塞感等症状,这种情况如果喂食不小心就容易诱发肺炎,出现发热、咳嗽咳痰等表现;

如果影响到手脚的活动,严重的病人可能会彻底偏瘫,病情相对轻的病人可能无法胜任简单的日常生活自理,举个简单的例子,比如说写字、拿筷子、拧毛巾这些动作,这些看似很简单的动作也完成不了,这也是脑梗塞的危害。

此外,脑梗后多种常见并发症

1、肺部感染:脑梗是病人最常见的并发症,有很多研究表明,肺部感染成为脑梗的最主要的致死因素。

2、心肌梗死:脑梗的常见并发症,有研究表明,很多脑梗病人,在急性期,常常伴有心肌缺血的表现,但是这种改变大部分病人在度过急性期后能够改变,有部分病人,可能发展成为心肌梗死。

3、尿路感染:见于留置导尿管的病人,或大小便失禁,得不到良好护理的病人,常常会导致尿路感染。

4、肾功能不全:也是造成病人死亡的重要并发症,主要与以下方面因素有关:脑梗是一种“应激”状态,体内高肾上腺素水平,容易造成肾动脉收缩,影响肾血流量。

5、脑梗后遗症:脑梗发病一年后仍有肢体、语言障碍等症状就属于后遗症了,医学上称之为脑梗的后遗症期。30%的脑梗患者会留下不同程度的后遗症,在我国30%-40%的脑梗患者面临复发。常见的后遗症有:肢体麻木、半侧肢体障碍、偏盲、偏瘫、失语。或者口眼歪斜、吞咽困难、呛食呛水、交叉性感觉障碍、交叉性瘫痪、眼球震颤、记忆力下降等。

脑梗塞对健康的影响不容小觑,引发脑梗塞的原因有哪些?

吸烟

吸烟是引起脑动脉粥样硬化的独立危险因素。在临床上往往见到30多岁的病人烟龄都快20年了。因此,避免患上脑梗塞疾病,戒烟才是最重要的。

熬夜

现在的人随着工作压力增加,熬夜已经成为家常便饭,但殊不知熬夜危害着我们的健康,甚至诱发脑梗塞的重要因素。

饮食

现在人大多都存在饮食不合理,饥一顿饱一顿的情况,而且很多还存在“无肉不欢”的情况,殊不知长期食油腻食物,对自身血管造成的负荷增加,久而久之很容易造成脑梗。

肥胖

肥胖是引起脑梗塞的高危因素,肥胖的人对血液压迫比较大,自然也比较容易使血流变慢,形成脑梗。

“三高”

高血压的发生会加快脑部动脉的硬化速度,从而引起脑梗。临床发现,高血压患者患脑梗的几率是普通人的6-7倍。所以,高血压患者若要避免患上脑梗,就要严格控制好自己的血压。

糖尿病患者一般均存在身体代谢功能紊乱的问题,而代谢紊乱可能会导致脑血管内形成血栓,进而堵塞脑血管,如此一来就会导致脑部血液出现供应障碍,最终诱发脑梗。

血脂增高会造成动脉粥样硬化,引起血管狭窄,动脉粥样硬化斑块形成,血压黏稠度增高,血流缓慢,导致脑梗。

心脏病

心脏是人体的“总司令部”,当心脏出现问题后,脑部供血自然也会出现问题,如此就会导致脑部出现缺血、缺氧等情况,进而导致脑梗发作。

温馨提示:

必须把血压、血脂和血糖控制在标准范围内,特别是血压,血压过高时会使得大脑内的微血管和小动脉破裂出血。但降血压速度不能过快,以免减慢血流量,增加血液黏稠而诱发各种意外。

保持情绪稳定,不能太激动。及时改变不良的生活习惯,如吸烟喝酒和暴饮暴食,采取低脂肪、低热量和低盐分的饮食结构。

脑梗死

 脑梗死,又称缺血性脑卒中,是一种血液供应受阻导致局部脑组织缺血性坏死或软化的脑血管疾病。常见类型包括大脑动脉粥样硬化型、心源性栓塞型、小动脉闭塞型等,发病原因主要与颈部大动脉粥样硬化、心源性栓塞和小动脉闭塞有关。高危人群主要包括中老年人,以及有高血压、心脏病、糖尿病及血脂异常等基础疾病的人群。

脑梗死的临床症状表现为局灶性神经功能缺损,可能呈现为偏瘫、感觉障碍、失语、共济失调等,重症病例可能进展为脑疝甚至脑死亡。并发症中常见的有肢体麻痹和肌肉运动障碍,讲话及吞咽困难,记忆减退和思考困难等。
对于脑梗死的治疗,需根据病因、发病机制、临床类型等因素选择个体化的治疗方案,旨在改善脑循环、保护神经、降低颅压等。有适应证者可考虑溶栓治疗,颈内动脉狭窄的患者或许可进行内膜切除术。此外,积极控制脑卒中的危险因素,如使用抗血小板聚集的药物,可以降低脑卒中的复发可能性。脑梗死的预后与神经功能缺损的严重程度、病因、并发症等多因素有关。
